monospace

Monospace type indicates commands within a paragraph, URLs, code in examples, text that appears on the screen, or text that you enter.

Forward slashes (/)

Forward slashes are used to separate the directory levels in a path to a UNIX server, directory, or file. Forward slashes are also used to separate parts of an Internet address. A forward slash will always be included at the end of a UNIX directory name and might or might not be included at the end of an Internet address.

Backward slashes (\)

Backward slashes are used to separate the levels in a path to a Windows server, directory, or file. A backward slash will always be included at the end of a Windows server, directory, or file path.

<install_dir>/

This notation refers to the location on your system of the main product installation directory.

Part I

Getting Started with Image Export

This section provides an introduction to the SDK.

Part I contains the following chapters:

- Chapter 1, "Introduction"

- Chapter 2, "Implementation Issues"

- Chapter 3, "Sample Applications"

1 Introduction

Image Export allows an Original Equipment Manufacturer (OEM) to translate almost any document, spreadsheet or presentation into one of several image formats.

Image Export's primary goal is to produce a faithful representation of the source file in a raster image format. There are several raster output format options, including JPEG, TIFF, Windows Bitmap, GIF and PNG. Through a C API, the developer can specify what source file should be exported, set various options that affect the content and structure of the output and specify the name and location of the output file(s) produced.

There may be references to other Outside In Technology SDKs within this manual. To obtain complete documentation for any other Outside In product, see:

http://www.oracle.com/technetwork/indexes/documentation/index.html#middleware

and click on Outside In Technology.

This chapter includes the following sections:

- Section 1.1, "What's New in this Release"

- Section 1.2, "Architectural Overview"

- Section 1.3, "Definition of Terms"

- Section 1.4, "Directory Structure"

- Section 1.5, "How to Use Image Export"

- Section 1.6, "Copyright Information"

1.1 What's New in this Release

- The updated list of supported formats is linked from the page http://www.outsideinsdk.com/. Look for the data sheet with the latest supported formats.

- Support has been added for AutoCAD 2013.

- The LibreOffice 4.0 suite (Impress, Draw, Calc, and Writer) is now supported.

- 64-bit zip compression is now supported in the zip input filter.

- Input filter support for HTML5 and CSS2.1 tags and attributes related to email messages has been added.

- Microsoft Visio 2010 is now supported.

- From Microsoft Office 2013, Access, OneNote, and Visio are now supported.

- From the Apple iWork suite, Pages (iPad) PDF Preview & Text, Numbers (iPad) PDF Preview & Text, and Keynote (iPad) PDF Preview & Text are supported.

- From the WordPerfect X6 suite, Word Processor, Quattro Pro, and Presentations are supported.

- Threading is now available on Linux x86-64 and Sun SPARC64.

- The 256-byte character limit has been removed for Export SDKs running under Transformation Server, enabling very long pathnames.

- Compiler support on Linux has been upgraded to the GNU GCC 4.x toolchain, which introduces a new dependency on libstdc++.so.6, removing the old dependency on libstdc++.so.5.

- Support has been added for both win-x86-32/win-x86-64 on Windows 8.1.

- A new option, SCCOPT_RENDER_EMBEDDED_FONTS, permits you to set whether fonts embedded in a file will be rendered.

- A new option, SCCOPT_STROKE_TEXT, is used to stroke out (display as graphical primitives) text in an AutoCAD file.

- A new option, SCCOPT_RENDER_DISABLEALPHABLENDING, allows you to disable alpha-channel blending (transparency) in rendering vector images.

- All Export products now support both a Java and .NET API. See Part III, "Using the Java API" and Part IV, "Using the .NET API" for more details.

1.2 Architectural Overview

The basic architecture of Outside In technologies is the same across all supported platforms:

Filter/Module

Description

Input Filter

The input filters form the base of the architecture. Each one reads a specific file format or set of related formats and sends the data to OIT through a standard set of function calls. There are more than 150 of these filters that read more than 600 distinct file formats. Filters are loaded on demand by the data access module.

Export Filter

Architecturally similar to input filters, export filters know how to write out a specific format based on information coming from the chunker module. The export filters generate TIFF, BMP, GIF, JPEG, and PNG.

Chunker

The Chunker module is responsible for caching a certain amount of data from the filter and returning this data to the export filter.

Export

The Export module implements the export API and understands how to load and run individual export filters.

Data Access

The Data Access module implements a generic API for access to files. It understands how to identify and load the correct filter for all the supported file formats. The module delivers to the developer a generic handle to the requested file, which can then be used to run more specialized processes, such as the Export process.

1.3 Definition of Terms

The following terms are used in this documentation.

Term

Definition

Developer

Someone integrating this technology into another technology or application. Most likely this is you, the reader.

Source File

The file the developer wishes to export.

Output File

The file being written: TIFF, BMP, GIF, JPEG, and PNG.

Page

A single raster image representation of a page of output. Page sizes will vary depending on the parameters used for an export (maximum size or scaling, etc.) and other options that affect the output type for rendered images.

Data Access Module

The core of Outside In Data Access, in the SCCDA library.

Data Access Submodule (also referred to as "Submodule")

This refers to any of the Outside In Data Access modules, including SCCEX (Export), but excluding SCCDA (Data Access).

Note: Image Export normally comes with only the SCCEX Submodule.

Document Handle (also referred to as "hDoc")

A Document Handle is created when a file is opened using Data Access (see Chapter 6, "Data Access Common Functions"). Each Document Handle may have any number of Subhandles.

Subhandle (also referred to as "hItem")

Any of the handles created by a Submodule's Open function. Every Subhandle has a Document Handle associated with it. For example, the hExport returned by EXOpenExport is a Subhandle. The DASetOption and DAGetOption functions in the Data Access Module may be called with any Subhandle or Document Handle. The DARetrieveDocHandle function returns the Document Handle associated with any Subhandle.

1.4 Directory Structure

Each Outside In product has an sdk directory, under which there is a subdirectory for each platform on which the product ships (for example, ix/sdk/ix_win-x86-32_sdk). Under each of these directories are the following three subdirectories:

- redist - Contains only the files that the customer is allowed to redistribute. These include all the compiled modules, filter support files, .xsd and .dtd files, cmmap000.bin, and third-party libraries, like freetype.

- sdk - Contains the other subdirectories that used to be at the root-level of an sdk (common, lib (windows only), resource, samplefiles, and samplecode (previously samples). In addition, one new subdirectory has been added, demo, that holds all of the compiled sample apps and other files that are needed to demo the products. These are files that the customer should not redistribute (.cfg files, exportmaps, etc.).

In the root platform directory (for example, ix/sdk/ix_win-x86-32_sdk), there are two files:

- README - Explains the contents of the sdk, and that makedemo must be run in order to use the sample applications.

- makedemo (either .bat or .sh – platform-based) - This script will either copy (on Windows) or Symlink (on Unix) the contents of …/redist into …/sdk/demo, so that sample applications can then be run out of the demo directory.

1.4.1 Installing Multiple SDKs

If you load more than one OIT SDK, you must copy files from the secondary installations into the top-level OIT SDK directory as follows:

- redist – copy all binaries into this directory.

- sdk – this directory has several subdirectories: common, demo, lib, resource, samplecode, samplefiles. In each case, copy all of the files from the secondary installation into the top-level OIT SDK subdirectory of the same name. If the top-level OIT SDK directory lacks any directories found in the directory being copied from, just copy those directories over.

1.5 How to Use Image Export

Here's a step-by-step overview of how to export a source file to an image file.

1. Call DAInitEx to initialize the Data Access technology. This function needs to be called only once per application. If using threading, then pass in the correct ThreadOption.

2. Set any options that require a NULL handle type (optional). Certain options need to be set before the desired source file is opened. These options are identified by requiring a NULL handle type. They include, but aren't limited to:

- SCCOPT_EX_CALLBACKS

- SCCOPT_EX_UNICODECALLBACKSTR

- SCCOPT_FALLBACKFORMAT

- SCCOPT_FIFLAGS

- SCCOPT_TEMPDIR

- SCCOPT_UNMAPPABLECHAR

3. Open the Source File. DAOpenDocument is called to create a document handle that uniquely identifies the source file. This handle may be used in subsequent calls to the EXOpenExport function or the open function of any other Data Access Submodule, and will be used to close the file when access is complete. This allows the file to be accessed from multiple Data Access Submodules without reopening.

4. Set the Options. If you require option values other than the default settings, call DASetOption to set options. Note that options listed in the Options Guide as having "Handle Types" that accept VTHEXPORT may be set any time before EXRunExport is called. For more information on options and how to set them, see Section 6.8, "DASetOption."

5. Open a Handle to Image Export. Using the document handle, EXOpenExport is called to obtain an export handle that identifies the file to the specific export product. This handle will be used in all subsequent calls to the specific export functions. The dwOutputId parameter of this function is used to specify that the output file type should be set to one of the following:

- FI_GIF

- FI_JPEGFIF

- FI_JPEG2000

- FI_PNG

- FI_BMP

- FI_TIFF

6. Make Any Required Calls to Annotation Functions. This is the point at which any calls to annotation functions (such as EXHiliteText, EXInsertText or EXHideText) should be made.

7. Export the File. EXRunExport is called to generate the output file(s) from the source file.

8. Close the Handle to Image Export. EXCloseExport is called to terminate the export process for the file. After this function is called, the export handle will no longer be valid, but the document handle may still be used.

9. Close the Source File. DACloseDocument is called to close the source file. After calling this function, the document handle will no longer be valid.

10. Close Image Export. DADeInit is called to de-initialize the Data Access technology.

2 Implementation Issues

This chapter covers some issues specific to using the Export products.

This chapter includes the following sections:

- Section 2.1, "Running in 24x7 Environments"

- Section 2.2, "Running in Multiple Threads or Processes"

- Section 2.3, "Image Export Issues"

2.1 Running in 24x7 Environments

To ensure robust 24x7 performance in server applications embedding the different export products, it is strongly recommended that the technology be run in a process separate from the server's primary process.

The file filtering technology underlying the technology represents almost a quarter of a million lines of code. This code is expected to robustly deal with any stream of bytes, of any length (any file), in all cases. Oracle has dedicated, and continues to dedicate, significant effort into making this technology extremely robust. However, in real world situations, expect that some small number of malformed files may force the filters into unstable states. This generally results in either a memory exception (which can be trapped and recovered from gracefully), infinite loop or a wild pointer that causes the filter to write into memory that is part of the same process but does not belong to the filter. In the latter situation, this wild pointer condition cannot be trapped.

On the desktop this is not a significant problem since the number of files being dealt with is relatively small. In a 24x7 server environment, however, a wild pointer can be extremely disruptive to the server process and produce serious problems. The best solution for dealing with this problem is to run any application that reads complex file formats in a separate process. This solution protects the application from the susceptibility of filtering technology to the unknown quality of input files.

It must be stressed that files that lead to wild pointers or infinite loops occur very infrequently, usually as a result of a third-party conversion process or beta versions of applications. Oracle is committed to addressing these issues and to updating and expanding its testing tools and corpus of documents to proactively minimize this "garbage in-garbage out" problem.

2.2 Running in Multiple Threads or Processes

On certain platforms, export products may be run in a multithreaded or multiprocessing application. The thing to remember when doing so is that each thread must go through all the steps listed in Chapter 1, "Introduction."

2.3 Image Export Issues

Four issues have been encountered when using Image Export:

- If a spreadsheet contains embedded graphics, embedded charts, or merged cells that cross page boundaries, Image Export does not clip these objects correctly. The objects appear in the correct position, but they bleed into the margins. In addition, some information may be duplicated on multiple pages as a result of this improper clipping. These errors should never result in information being omitted from the output.

- When processing fonts that are not TrueType fonts, the output graphic will contain text that appears "blocky" as a result of shortcomings in Image Export's smoothing algorithm.

- There is currently no method of specifying how wide a field in a database should be. Occasionally this will lead to situations where information in a database field will not be included in the output graphic, resulting in a loss of content.

- If multiple pages of garbage output occur when exporting images, it is possible that the default setting of the SCCOPT_FALLBACKFORMAT (FallbackFormatEnum on the server version) option (FI_ASCII-8) is forcing the technology to attempt to read files that it cannot identify as text. Setting the pertinent option to the value FI_NONE prevents the software from exporting unidentified binary files as though they were text.

3 Sample Applications

Each of the sample applications included in this SDK is designed to highlight a specific aspect of the technology's functionality. We ship built versions of these sample applications. The compiled executables should be in the root directory where the product is installed.

The following copyright applies to all sample applications shipped with this product:

Copyright © Oracle 1993, 2014

All rights reserved.

You have a royalty-free right to use, modify, reproduce and distribute the Sample Applications (and/or any modified version) in any way you find useful, provided that you agree that Oracle has no warranty obligations or liability for any Sample Application files.

This chapter includes the following sections:

- Section 3.1, "Building the Samples on a Windows System"

- Section 3.2, "An Overview of the Sample Applications"

- Section 3.3, "Accessing the SDK via a Java Wrapper"

3.1 Building the Samples on a Windows System

Microsoft Visual Studio project files are provided for building each of the sample applications. For 32-bit versions of Windows, versions of the project files are provided for Visual Studio 6 (.dsp files) and Visual Studio 2005 (.vcproj files).

Because .vcproj files may not pick up the right compiler on their own, you need to make sure that you are building with the Win64 configuration in Visual Studio 2005. For 64-bit versions of Windows, only the Visual Studio 2005 versions are available.

The project files for the sample applications can be found in the samplecode\win subdirectory of the Outside In SDK.

For specific information about building the sample applications on your UNIX OS, see Chapter 5, "UNIX Implementation Details."

3.2 An Overview of the Sample Applications

Here's a quick tour of the sample applications provided with this product. Not all of the sample applications are provided for both the Windows and UNIX platforms. See the heading of each application's subsection for clarification.

This section describes the following sample applications.

- Section 3.2.1, "*sample"

- Section 3.2.2, "export (Windows Only)"

- Section 3.2.3, "exsimple"

- Section 3.2.4, "exredir"

- Section 3.2.5, "extract_archive"

- Section 3.2.6, "ixanno"

3.2.1 *sample

The name of this sample application varies according to product (ixsample for Image Export).

The following is a basic implementation that uses the default settings for every option.

ixsample Inputfile Outputfile

This sample is provided for instructional value rather than functionality. The output format is always TIF. As an exercise, you may want to try changing the EXOpenExport() call in the application so that it outputs a different graphic type.

3.2.2 export (Windows Only)

This application was designed to facilitate the testing of the software and should not be assumed to be of commercial quality.

Important:

No default options are set at initial runtime. The time the software is used, click the Options button and set the options. Failure to do this generates export errors.

The application allows the user to run a single source file. The user can select the source file, an output file and set the various options.

3.2.2.1 The export Main Window

The following figure shows the Main Window for the export application.

Figure 3-1 export Main Window for Image Export

The Main Window is composed of several elements, discussed here.

- Output Format menu: This menu allows the user to select the type of output to generate. An entry for the format(s) you license will appear in this menu.

- Options button: This opens up a new dialog with one or more tabs exposing the options for the selected product.

- Source document field: This is the document to be exported. Click the Browse button to pick the source file, or type in the path name.

- 'Export to' field: This is the initial resulting output file. Type in a file name or use the Browse button to select a file. Other output files are named based on the one chosen here.

- Delete button: Clicking this button deletes all files generated by the last export, listed in the Status: field. This is useful when multiple output files are produced because the default naming rules do not overwrite an existing file. If you run Export over and over again with the same output file name, you can produce a large number of files. Clicking Delete before each export solves this problem.

- 'After Export, view output file with default application' checkbox: If the export was successful, checking this box launches the initial output file in the application associated with the output flavor's default extension.

- Export button: Click this button to start the export process once you've determined the export settings.

- Exit button: Click to close the Export application.

3.2.3 exsimple

This simple command line driven program allows the user to run a single source file through the software. The user can select the source file and output file and set the various options.

To run the program, type:

exsimple in_file out_file config_file

- in_file is the input file to be converted

- out_file is the output location

- config_file is the configuration file that sets the conversion options. If no configuration file is specified, default.cfg in the current directory is used.

The configuration file is a text file used to set the conversion options. We recommend reading through the configuration file for more information about valid options and their values (use of invalid options results in exsimple not producing output).

Follow these instructions to set configurable options.

- Set the Output ID before running the software. It is required and must not be omitted. It is also recommended that you set SCCOPT_FALLBACKFORMAT to FI_NONE. This prevents the export of unidentified binary files as though they were text, which could generate pages of garbage output.

3.2.4 exredir

This sample application is based on the exsimple sample application. It is designed to demonstrate how to use redirected IO and callbacks when using the software. It takes the same arguments and command line structure as exsimple and the same configuration files can be used. For details, see Section 3.2.3, "exsimple."

3.2.5 extract_archive

extract_archive demonstrates using the DATree API to extract all nodes in an archive.

The application is executed from the command line and takes two parameters, the name of the input file and the name of an output directory for the extracted files:

extract_archive input_file output_directory

3.2.6 ixanno

This sample application is provided more for the instructional value its sample code offers than for the functionality it provides when executed. It primarily works as an example of how to integrate Content Access with Image Export. This particular application does search hit highlighting. However, the general principles of how to get ACC text positions from Content Access should be evident from perusing the source code.

This command takes the following parameters:

- InputFile

- OutputFIle

- HiliteString

When using Image Export, the output type is always TIF.

The following sample command line demonstrates this command:

ixanno InputFile OutputFile HiliteString

A license for Content Access or Search Export is required to enable use of any of the annotation features supported by Image Export. Contact your Outside In sales representative for more information.

3.3 Accessing the SDK via a Java Wrapper

The ExJava Java wrapper, working in tandem with the exporter sample application, provides a working example of one method of interfacing with Oracle's C-based SDK products from a Java application. Export.jar is a Java API wrapper used by a Java application to control the exporter executable and set conversion options. exporter is a C-based executable which performs conversions using the modules in the Outside In SDK.

The exporter executable should be placed in the root directory of the Outside In SDK being used. If more than one Outside In SDK is being used, the contents of each SDK should be unpacked to the same root directory. Export.jar should be placed somewhere in your classpath.

On UNIX systems this sample application must be run from the directory containing the Outside In technology.Java version 1.6 or higher is required to run this sample application.

3.3.1 The ExJava Wrapper API

The JavaDocs documentation for the Java API is provided in the /sdk//samplecode/ExJava/docs directory. Conversion options are set using the ExportProperties.

Additionally, the appropriate .cfg file for the ExportTest sample application found in the Examples/ExportTest directory may provide further insight as to what properties are available and how they correspond to options and values for options.

The Export.jar and its source code can be found in the Java API directory. Place Export.jar somewhere in your classpath. In order to use the ExportTest sample application (which demonstrates how a Java application can use the ExJava API) without modifying your system configuration or the ExJava sample application, you should place the Export.jar file in the root directory of the Outside In SDK product you are using.

3.3.2 The C-Based Exporter Application

This is a standalone executable that runs out of process from the Java API. The Java API controls the conversion through command line parameters that are passed to the executable. After the conversion completes, the executable returns a conversion status code to the Java API. The command line parameters are base-64 encoded to allow for the use of Unicode encoded paths.

As the exporter executable is a C-based application, you will need to make sure the Java API can find the version of exporter appropriate for the platform you are using. Generally, and specifically for the purpose of using the ExportTest sample application, the correct executable should be copied to the root directory of the Oracle export SDK product you are using.

A compiled version of the C exporter program is included in the SDK with the rest of the Outside In binaries. The source for exporter is located in the /sdk/samplecode/ExJava/exporter directory.

The current implementation of ExJava may not produce an error if it cannot find the exporter application. This known issue may be corrected in a future version of ExJava.

3.3.3 Compiling the Executables

A Microsoft Visual Studio 6.0 project file and a UNIX makefile are provided in Exporter/Win and Exporter/Unix, respectively, so that you can modify the Exporter executable or compile it for a platform other than those for which compiled versions of exporter are provided. If you unpacked the ExJava package into the root directory of one of Oracle's export SDK products, you should be able to use the Visual Studio Project and makefile as is. Otherwise, you will need to edit them in order to provide paths to the Oracle export SDK include and library files.

If you are compiling ExJava for use on the Solaris platform, make sure your LD_LIBRARY_PATH contains the Outside In SDK path before trying to build the Exporter module.

3.3.4 The ExportTest Sample Application

ExportTest is an example of how a Java developer could use the ExJava wrapper to use one of the Outside In SDKs. The following is a list of the components that should be placed in the root directory of the Outside In SDK you are using in order to run this sample application:

1. Export.jar (from the Java API directory)

2. Exporter module for the platform you wish to use (located in the /sdk/samplecode/ExJava/Exporter/Win or /sdk/samplecode/ExJava/Exporter/Unix directory, depending on which platform you are using)

3. ix.cfg file (also in Examples/ExportTest directory)

4. If you are running ExportTest on a UNIX system, make sure to edit the .cfg file so it reflects the correct name of the exporter module you renamed.

5. ExportTest.jar (also in Examples/ExportTest directory)

6. The appropriate batch file to run the ExportTest application (ExportTest.bat for Windows and ExportTest.sh for UNIX, both located in the Examples/ExportTest directory)

Once these files are properly copied, execute the batch file with the name/path of an input file to convert, the name for the base output file and the name of the configuration file to use for setting conversion options.

ExportTest.jar uses the contents of the configuration file to determine what option/value pairs it should use when doing the conversion. It is not necessary to use a configuration file when developing your own application.

3.3.5 An Example Conversion Using the ExJava Wrapper

This is a simple outline of the steps for using the ExJava wrapper on a Windows system to convert a Word document called MyWordDoc.Doc. For information about properly setting up your environment to use the Outside In SDK in a UNIX environment, see: Chapter 5, "UNIX Implementation Details."

1. Edit the .cfg file and make sure outputid is set to the FI* value appropriate for the Outside In product you've licensed. Alter any other parameters in the .cfg file as needed then save the file.

2. Execute the following command. The sample command below assumes BMP as the export type. Change this type accordingly:

ExportTest.bat myworddoc.doc output.bmp ix.cfg

Click on Outside In Technology, then click the Certification Information PDF.

The 64-bit version of sccvw.dll will not load on an AMD-64 system without Visual C++ runtime version 8 installed. This happens because the system is missing the msvcr80.dll library, which is required. Users can download the required library from the following location:

http://www.microsoft.com/downloads/details.aspx?FamilyId=90548130-4468-4BBC-9673-D6ACABD5D13B&displaylang=en

This chapter includes the following sections:

- Section 4.1, "Installation"

- Section 4.2, "Libraries and Structure"

- Section 4.3, "The Basics"

- Section 4.4, "Default Font Aliases"

- Section 4.5, "Changing Resources"

4.1 Installation

To install the demo version of the SDK, copy the contents of the ZIP archive (available on the web site) to a local directory of your choice.

This product requires the Visual C++ libraries included in the Visual C++ Redistributable Package available from Microsoft. There are three versions of this package (x86, x64, and IA64) for each corresponding version of Windows. These can be downloaded from www.microsoft.com/downloads, by searching on the site for the following packages:

- vcredist_x86.exe

- vcredist_x64.exe

- vcredist_IA64.exe

The required download version is the "2005 SP1 Redistributable Package."

Outside In requires the msvcr80.dll redistributable module.

The installation directory should contain the following directory structure.

Directory

4.1.1 NSF Support

Notes Storage Format (NSF) files are produced by the Lotus Notes Client or the Lotus Domino server. The NSF filter is the only Outside In filter that requires the native application to be present to filter the input documents. Due to integration with an outside application, NSF support will not work with redirected I/O, when an NSF file is embedded in another file, or with IOTYPE_UNICODEPATH. Either Lotus Notes version 8 or Lotus Domino version 8 must be installed on the same machine as OIT. A 32-bit version of the Lotus software must be used if you are using a 32-bit version of OIT. A 64-bit version of the Lotus software must be used if you are using a 64-bit version of OIT. On Windows, SCCOPT_LOTUSNOTESDIRECTORY should be set to the directory containing the nnotes.dll. NSF support is only available on the Win32 , Win x86-64, Linux x86-32, and Solaris Sparc 32 platforms.

4.2 Libraries and Structure

The following is an overview of the files in the main installation directory for all five Outside In export products.

4.3 The Basics

The following is a discussion of some basic usage and installation features.

All the steps outlined in this section are used in the sample applications provided with the SDK. Looking at the code for the exsimple sample application is recommended for those wishing to see a real-world example of this process.

4.3.1 What You Need in Your Source Code

Any source code that uses this product should #include the file sccex.h and #define WINDOWS and WIN32 or WIN64. For example, a Windows application might have a source file with the following lines:

#define WINDOWS         /* Will be automatically defined if your
compiler defines _WINDOWS */
#define WIN32
#include <sccex.h>

The developer's application should be linked to the product DLLs through the provided libraries.

4.3.2 Options and Information Storage

This software is based on the Outside In Viewer Technology (or simply "Viewer Technology"). When using the Export products, a list of available filters and a list of available display engines are built by the technology, usually the first time the product runs. You do not need to ship these lists with your application. The lists are automatically recreated if corrupted or deleted.

The files used to store this information are stored in an .oit subdirectory in \Documents and Settings\user name\Application Data.

If an .oit directory does not exist in the user's directory, the directory is created automatically. The files are automatically regenerated if corrupted or deleted.

The files are:

- *.f = Filter lists

- *.d = Display Engine lists

- *.opt = Persistent options

Some applications and services may run under a local system account for which there is no users "application data" folder. The technology first does a check for an environment variable called OIT_DATA_PATH. Then it checks for APPDATA, and then LOCALAPPDATA. If none of those exist, the options files are put into the executable path of the UT module.

These file names are intended to be unique enough to avoid conflict for any combination of machine name and install directory. This allows the user to run products in separate directories without having to reload the files above. The file names are built from an 11-character string derived from the directory the Outside In technology resides in and the name of the machine it is being run on. The string is generated by code derived from the RSA Data Security, Inc. MD5 Message-Digest Algorithm.

The software still functions if these lists cannot be created for some reason. In that situation, however, significant performance degradation should be expected.

4.3.3 Structure Alignment

Outside In is built with 8-byte structure alignment. This is the default setting for most Windows compilers. This and other compiler options that should be used are demonstrated in the files provided with the sample applications in samples\win.

4.3.4 Character Sets

The strings passed in the Windows API are ANSI1252 by default.

To optimize performance on systems that do not require DBCS support, a second character mapping bin file, that does not contain any of the DBCS pages, is now included. The second bin file gives additional performance benefits for English documents, but cannot handle DBCS documents. To use the new bin file, replace the cmmap000.bin with the new bin file, cmmap000.sbc. For clarity, a copy of the cmmap000.bin file (cmmap000.dbc) is also included. Both cmmap000.sbc and cmmap000.dbc are located in the \common directory of the technology.

4.3.5 Runtime Considerations

The files used by the product must be in the same directory as the developer's executable.

4.4 Default Font Aliases

The technology includes the following default font alias map for Windows. The first value is the original font, the second is the alias.

- Chicago = Arial

- Geneva = Arial

- New York = Times New Roman

- Helvetica = Arial

- Helv = Arial

- times = Times New Roman

- Times = Times New Roman

- Tms Roman = Times New Roman

- itc zapfdingbats = Zapfdinbats

- itc zapf dingbats = Zapfdinbats

4.5 Changing Resources

Outside In Image Export ships with the necessary files for OEMs to change any of the strings in the technology as they see fit.

Strings are stored in the lodlgstr.h file found in the resource directory. The file can be edited using any text editor.

Note:

Do not directly edit the scclo.rc file. Strings are saved with their identifiers in lodlgstr.h. If a new scclo.rc file is saved, it will contain numeric identifiers for strings, instead of their #define'd names.

Once the changes have been made, the updated scclo.dll file can be rebuilt using the following steps:

1. Compile the .res file:

rc /fo ".\scclo.res" /i "<path to header (.h) files folder>" /d "NDEBUG" scclo.rc

2. Link the scclo.res file you've created with the scclo.obj file found in the resource directory to create a new scclo.dll:

link /DLL /OUT:scclo.dll scclo.obj scclo.res

Note:

Developers should make sure they have set up their environment variables to build the library for their specific architecture. For Windows x86_32, when compiling with VS 2005, the solution is to run vsvars32.bat (in a standard VS 2005 installation, this is found in C:\Program Files\Microsoft Visual Studio 8\Common7\Tools\). If this works correctly, you will see the statement, "Setting environment for using Microsoft Visual Studio 2005 x86 tools." If you do not complete this step, you may have conflicts that lead to unresolved symbols due to conflicts with the Microsoft CRT.

3. Embed the manifest (which is created in the \resource directory during step 2) into the new DLL:

mt -manifest scclo.dll.manifest -outputresource:scclo.dll;2

If you are not using Microsoft Visual Studio, substitute the appropriate development tools from your environment.

Note:

In previous versions of Outside In, it was possible to directly edit the SCCLO.DLL using Microsoft Visual Studio. Outside In DLLs are now digitally signed. Editing the signed DLL is not advisable.

5 UNIX Implementation Details

The UNIX implementation of the Export product set is delivered as a set of shared libraries. For a list of the currently supported platforms, see:

http://www.oracle.com/technetwork/indexes/documentation/index.html#middleware

- Section 5.12, "Oracle Solaris Compiling and Linking"

5.1 Installation

To install the demo version of the SDK, copy the tgz file corresponding to your platform (available on the web site) to a local directory of your choice. Decompress the tgz file and then extract from the resulting tar file as follows:

gunzip tgzfile
tar xvf tarfile

The installation directory should contain the following directory structure.

Directory

Description

/redist

Contains a working copy of the UNIX version of the technology.

/sdk/common

Contains the C include files needed to build or rebuild the technology.

/sdk/demo

Contains the compiled executables of the sample applications.

/sdk/resource

Contains localization resource files. For details, see Section 5.8, "Changing Resources."

/sdk/samplecode

Contains a subdirectory holding the source code for a sample application. For details, see Chapter 3, "Sample Applications."

/sdk/samplefiles

Contains sample input files authored in a variety of popular graphics, word processor, compression, spreadsheet and presentation applications.

5.1.1 NSF Support

Notes Storage Format (NSF) files are produced by the Lotus Notes Client or the Lotus Domino server. The NSF filter is the only Outside In filter that requires the native application to be present to filter the input documents. Due to integration with an outside application, NSF support will not work with redirected I/O nor will it work when an NSF file is embedded in another file. Lotus Domino version 8 must be installed on the same machine as OIT. The NSF filter is currently only supported on the Win32, Win x86-64, Linux x86-32, and Solaris Sparc 32 platforms. SCCOPT_LOTUSNOTESDIRECTORY is a Windows-only option and is ignored on Unix.

Additional steps must be taken to prepare the system. It is necessary to know the name of the directory in which Lotus Domino has been installed. On Linux, this default directory is /opt/ibm/lotus/notes/latest/linux. On Solaris, it is /opt/ibm/lotus/notes/latest/sunspa.

- In the Lotus Domino directory, check for the existence of a file called "notes.ini". If the file "notes.ini" does not exist, create it in that directory and ensure that it contains the following single line:
[Notes]

- Add the Lotus Domino directory to the $LD_LIBRARY_PATH environment variable.

- Set the environment variable $Notes_ExecDirectory to the Lotus Domino directory.

5.2 Libraries and Structure

On UNIX platforms the Outside In products are delivered with a set of shared libraries. All libraries should be installed to a single directory. Depending upon your application, you may also need to add that directory to the system's runtime search path. For more details, see Section 5.6, "Environment Variables."

The following is a brief description of the included libraries and support files. In instances where a file extension is listed as .*, the file extension varies for each UNIX platform (sl on HP-UX, so on Linux and Solaris).

5.3 The Basics

Sample applications are provided with the SDK. These applications demonstrate most of the concepts described in this manual. For a complete description of the sample applications, see Chapter 3, "Sample Applications."

5.3.1 What You Need in Your Source Code

Any source code that uses this product should #include the file sccex.h and #define UNIX. For example, a 32-bit UNIX application might have a source file with the following lines:

#define UNIX
#include <sccex.h>

and a 64-bit UNIX application might have a source file with the following lines:

#define UNIX
#define UNIX_64
#include <sccex.h>

5.3.2 Information Storage

This software is based on the Outside In Viewer Technology (or simply "Viewer Technology"). A file of default options is always created, and a list of available display engines is also built by the technology, usually the first time the product runs (for UNIX implementations). You do not need to ship these lists with your application.

Lists are stored in the $HOME/.oit directory. If the $HOME environment variable is not set, the files are put in the same directory as the Outside In Technology. If an /.oit directory does not exist in the user's $HOME directory, the .oit directory is created automatically by the technology. The files are automatically regenerated if corrupted or deleted.

The files are:

- *.d: Display engine list

- *.opt: Persistent options

The technology does not actually use the list of default options created by the Viewer Technology.

The filenames are intended to be unique enough to avoid conflict for any combination of machine name and install directory. This is intended to prevent problems with version conflicts when multiple versions of the Viewer Technology and/or other Viewer Technology-based products are installed on a single system. The filenames are built from an 11-character string derived from the directory the Outside In technology resides in and the name of the machine it is being run on. The string is generated by code derived from the RSA Data Security, Inc. MD5 Message-Digest Algorithm.

The products still function if these files cannot be created for some reason. In that situation, however, significant performance degradation should be expected.

5.4 Character Sets

The strings passed in the UNIX API are ISO8859-1 by default.

To optimize performance on systems that do not require DBCS support, a second character mapping bin file, that does not contain any of the DBCS pages, is now included. The second bin file gives additional performance benefits for English documents, but cannot handle DBCS documents. To use the new bin file, replace the cmmap000.bin with the new bin file, cmmap000.sbc. For clarity, a copy of the cmmap000.bin file (cmmap000.dbc) is also included. Both cmmap000.sbc and cmmap000.dbc are located in the /sdk/common directory of the technology.

5.5 Runtime Considerations

The following is information to consider during run-time.

5.5.1 X Server Requirement

Note:

The X Server requirement can be eliminated by setting the SCCOPT_RENDERING_PREFER_OIT option to TRUE.

Access to a running X Windows server and the presence of Motif (or LessTif on Linux) are required to convert from non-raster or vector formats on UNIX systems. Examples of non-raster/vector graphics files include CAD drawings and presentation files such as Power Point 97 files. Bitmap graphic conversion (handled in XML Export by the libde_bmp.* engine) does not require access to a running X Windows server. Examples of bitmap file formats include GIF, JPEG, TIFF, and Windows BMP files.

A runtime check for the presence of X libraries is performed to accommodate system with and without available X servers. This check looks on the system-specific library path variable for the X libraries. If the X libraries are not found, this product does not perform vector graphics conversion.

Be sure to set the $DISPLAY environment variable before running this product when non-raster/vector graphic conversion is needed. This is especially important to remember in situations such as CGI programs that start with a limited environment.

For example, when running the technology from a remote session, setting DISPLAY=:0.0 tells the system to use the X Windows server on the console.

5.5.2 OLE2 Objects

Some documents that the developer is attempting to convert may contain embedded OLE2 objects. There are platform-dependent limits on what the technology can do with OLE2 objects. However, Outside In attempts to take advantage of the fact that some documents accompany an OLE2 embedding with a graphic "snapshot," in the form of a Windows metafile.

On all platforms, when a metafile snapshot is available, the technology uses it to convert the object. When a metafile snapshot is not available on UNIX platforms, the technology is unable to convert the OLE2 object.

5.5.3 Machine-Dependent Graphics Context

The system uses a machine configuration dependent graphics context to render some images. The number of colors available in the systems graphics context is a particularly important limiting factor. For example, if the video driver for a system running Outside In is set up to display 256 colors, images produced on that system would be limited to 256 colors.

- For all vector image formats that HX converts, we require that the X11 display support either 1 bit, 4 bits, 8 bits, 24 bits, or 32 bits.

- If SCCOPT_RENDERING_PREFER_OIT = TRUE on UNIX then we're using internal rendering of vector formats, and we don't use the X11 display.

- Raster image formats when converted do not need the X11 display, so are not sensitive to the bit depth of the display.

Note:

SCCOPT_RENDERING_PREFER_OIT is supported on Linux x86-32, Linux x86-64, Solaris Sparc-32, IBM AIX 32-bit, and HP-UX RISC 32-bit platforms.

5.5.4 Signal Handling

These products trap and handle the following signals:

- SIGABRT

- SIGBUS

- SIGFPE

- SIGILL

- SIGINT

- SIGSEGV

- SIGTERM

Developers who wish to override our default handling of these signals should set up their own signal handlers. This may be safely done after the developer's application has called DAInitEx().

Note:

The Java Native Interface (JNI) allows Java code to call and be called by native code (C/C++ in the case of OIT). You may run into problems if Java isn't allowed to handle signals and forward them to OIT. If OIT catches the signals and forwards them to Java, the JVMs will sometimes crash. OIT installs signal handlers when DAInitEx() is called, so if you call OIT after the JVM is created, you will need to use libjsig. Refer here for more information:

http://www.oracle.com/technetwork/java/javase/index-137495.html

5.5.5 Runtime Search Path and $ORIGIN

Libraries and sample applications are all built with the $ORIGIN variable as part of the binaries' runtime search path. This means that at runtime, OIT libraries will automatically look in the directory they were loaded from to find their dependent libraries. You don't necessarily need to include the technology directory in your LD_LIBRARY_PATH or SHLIB_PATH.

As an example, an application that resides in the same directory as the OIT libraries and includes $ORIGIN in its runtime search path will have its dependent OIT libraries found automatically. You will still need to include the technology directory in your linker's search path at link time using something like -L and possibly -rpath-link.

Another example is an application that loads OIT libraries from a known directory. The loading of the first OIT library will locate the dependent libraries.

Note:

This feature does not work on AIX and FreeBSD.

5.6 Environment Variables

Several environment variables may be used at run time. Following is a short summary of those variables and their usage.

Variable

Description

$LD_LIBRARY_PATH (FreeBSD, HP-UX Itanium 64, Linux, Solaris)

$SHLIB_PATH (HP-UX RISC 32)

$LIBPATH (AIX, iSeries)

These variables help your system's dynamic loader locate objects at runtime. If you have problems with libraries failing to load, try adding the path to the Outside In libraries to the appropriate environment variable. See your system's manual for the dynamic loader and its configuration for details.

Note that for products that have a 64-bit PA/RISC, 64-bit Solaris and Linux PPC/PPC64 distributable, they will also go under $LD_LIBRARY_PATH.

$DISPLAY

Must be set to point to a valid X Server to render files, unless you plan to use the SCCOPT_RENDERING_PREFER_OIT option. For details, see Section 5.5.1, "X Server Requirement."

$GDFONTPATH

Must be set if you intend to use the SCCOPT_RENDERING_PREFER_OIT option. This variable includes one or more paths to fonts for use with Outside In's internal graphics rendering code.

$HOME

Must be set to allow the system to write the option, filter and display engine lists. For details, see Section 5.3.2, "Information Storage."

5.8 Changing Resources

All of the strings used in the UNIX versions of Outside In products are contained in the lodlgstr.h file. This file, located in the resource directory, can be modified for internationalization and other purposes. Everything necessary to rebuild the resource library to use the modified source file is included with the SDK.

In addition to lodlgstr.h, the scclo.o object file is provided. This is necessary for the linking phase of the build. A makefile has also been provided for building the library. The makefile allows building on all of the UNIX platforms supported by Outside In. It may be necessary to make minor modifications to the makefile so the system header files and libraries can be found for compiling and linking.

Standard INCLUDE and LIB make variables are defined for each platform in the makefile. Edit these variables to point to the header files and libraries on your particular system. Other make variables are:

- TECHINCLUDE: May need to be edited to point to the location of the Outside In /common header files supplied with the SDK.

- BUILDDIR: May need to be edited to point to the location of the makefile, lodlgstr.h, and scclo.o (which should all be in the same directory).

After these variables are set, change to the build directory and type make. The libsc_lo resource library is built and placed in the appropriate platform-specific directory. To use this library, copy it into the directory where the Outside In product is stored and the new, modified resource strings are used by the technology.

Menu constants are included in lomenu.h in the common directory.

5.9 HP-UX Compiling and Linking

The libsc_ex.sl and libsc_da.sl libraries are the only ones that must be linked with your application. They can be loaded when your application starts by linking them directly at compile time or they can be loaded dynamically by your application using library load functions (for example, shl_load).

To use Image Export's annotation functions, you also must link to libsc_ca.sl, requiring a separate license to Outside In Content Access or Search Export. Contact your Outside In sales representative for more information.

The shared libraries are dependent on the presence of the X libraries Xm, Xt and X11 if vector graphics support is required. It is the application developer's responsibility to ensure that the needed functions from these libraries are present before the product libraries are used.

The following is an example command line used to compile the sample application exsimple from the /sdk/samplecode directory. The command lines are separated into sections for HP-UX and HP-UX on Itanium (which requires GCC). This command line is only an example. The actual command line required on the developer's system may vary. The example assumes that the include and library file search paths for the technology libraries and any required X libraries are set correctly. If they are not set correctly, the search paths for the include and/or library files must be explicitly specified via the -I include file path and/or -L library file path options, respectively, so that the compiler and linker can locate all required files.

5.9.1 HP-UX on RISC

cc -w -o ../exsimple/unix/exsimple ../exsimple/unix/exsimple.c +DAportable -Ae -I/usr/include -I../../common -L../../demo -L/usr/lib -lsc_ex -lsc_da -Wl,+s,+b,'$ORIGIN'

5.9.2 HP-UX on RISC (64 bit)

cc -w -o ../exsimple/unix/exsimple ../exsimple/unix/exsimple.c +DD64 -I/usr/include -I../../common -L../../demo -L/usr/lib/pa20_64 -DUNIX_64 -lsc_ex -lsc_da -Wl,+s,+b,'$ORIGIN'

5.10 IBM AIX Compiling and Linking

All libraries should be installed into a single directory and the directory must be included in the system's shared library path ($LIBPATH). $LIBPATH must be set and must point to the directory containing the Outside In Technology.

Outside In technology has been updated to increase performance, at a cost of using more memory. It is possible that this increased memory usage may cause a problem on AIX systems, which can be very conservative in the amount of memory they grant to processes. If your application experiences problems due to memory limitations with Outside In, you may be able to fix this problem by using the "large page" memory model.

If you anticipate viewing or converting very large files with Outside In technology, we recommend linking your applications with the -bmaxdata flag. For example:

cc -o foo foo.c -bmaxdata:0x80000000

If you are currently seeing "illegal instruction" errors followed by immediate program exit, this is likely due to not using the large data model.

To use the Image Export annotation function, you must also link to libsc_ca.sl, requiring a separate license to Outside In Content Access or Search Export. Contact your Outside In sales representative for more information.

The shared libraries are dependent on the presence of the X libraries Xm, Xt and X11 if vector graphics support is required. It is the application developer's responsibility to ensure that the needed functions from these libraries are present before the product libraries are used.

The following is an example command line used to compile the sample application exsimple from the /sdk/samplecode directory. This command line is only an example. The actual command line required on the developer's system may vary. The example assumes that the include and library file search paths for the technology libraries and any required X libraries are set correctly. If they are not set correctly, the search paths for the include and/or library files must be explicitly specified via the -I include file path and/or -Llibrary file path options, respectively, so that the compiler and linker can locate all required files. Developers need to pass -brtl to the linker to list libraries in the link command as dependencies of their applications.

Developers may need to use the -qcpluscmt flag to allow C++ style comments.

gcc -w -o ../exsimple/unix/exsimple ../exsimple/unix/exsimple.c -I../../common -L../../demo -lsc_ex -lsc_da -DFUNCPROTO -Wl,-brtl

5.11 Linux Compiling and Linking

This section discusses issues involving Linux compiling and linking.

5.11.1 Library Compatibility

This section discusses Linux compatibility issues when using libraries.

5.11.1.1 Motif Libraries

Problems can be seen when using Export products and trying to convert graphics files. For example, zero-byte graphics files are generated if the technology cannot find the proper Motif library. You can check to see if this is the case by running the following command:

ldd libos_xwin.so

This prints a list of the dependencies that this library has. If the line for the Motif library is similar to the following then your system may not have a compatible Motif library:

libXm.so.3 => not found

The solution is to install a compatible Motif library and use it to build your application. Often, the installation discs for your particular Linux platform have the proper libraries. If your installation discs do not have the libraries, instructions for downloading a binary rpm can be found at http://rpmfind.net/linux/RPM.

If you are doing development, you must use the proper header files, as well.

The following is the Motif library version used by Oracle when building and testing the Outside In binaries.

- x86 Linux - OpenMotif v. 2.2.3

If a directory needs to be specified for the compiler to find the shared libraries, the $LD_LIBRARY_PATH environment variable is recommended. This prevents the compiler from hard-coding the library's current directory into the executable as the only directory to search for the library at run time. Instead, the system first searches the directories specified by $LD_LIBRARY_PATH for the library.

5.11.1.2 GLIBC and Compiler Versions

The following table indicates the compiler version used and the minimum required version of the GNU standard C library needed for Outside In operation.

Distribution

Compiler Version

GLIBC Version

x86 Linux

3.3.2

libc.so.6 (2.3.2 or newer)

5.11.1.3 Other Libraries

In addition to libc.so.6, Outside In is dependent upon the following libraries:

- libXm.so.3 (in particular, libXm.so.3.0.2 or newer, due to issues in OpenMotif 2.2.2)

- libXt.so.6

- libstdc++.so.6

- libgcc_so.1

libgcc_s.so.1 was introduced with GCC 3.0, so any distribution based on a pre-GCC 3.0 compiler does not include libgcc_s.so.1.

5.11.2 Compiling and Linking

The libsc_ex.so and libsc_da.so are the only libraries that must be linked with your applications. They can be loaded when your application starts by linking them directly at compile time or they can be loaded dynamically by your application using library load functions (for example, dlopen).

To use Image Export annotation functions, you must also link to libsc_ca.so, requiring a separate license to Outside In Content Access or Search Export. Contact your Outside In sales representative for more information.

The shared libraries are dependent on the presence of the X libraries Xm, Xt and X11 if vector graphics support is required. It is the application developer's responsibility to ensure that the needed functions from these libraries are present before the product libraries are used.

The following are example command lines used to compile the sample application exsimple from the /sdk/samplecode directory. This command line is only an example. The actual command line required on the developer's system may vary.

The example assumes that the include and library file search paths for the technology libraries and any required X libraries are set correctly. If they are not set correctly, the search paths for the include and/or library files must be explicitly specified via the -I include file path and/or -L library file path options, respectively, so the compiler and linker can locate all required files.

The -L/usr/X11R6/lib option is also available.

5.11.2.1 Linux 32-bit

gcc -w -o ../exsimple/unix/exsimple ../exsimple/unix/exsimple.c -I/usr/local/include -I../../common -L../../demo -L/usr/local/lib -lsc_ex -lsc_da -Wl,-rpath,../../demo -Wl,-rpath,'${ORIGIN}'

5.11.2.2 Linux 64-bit

gcc -w -o ../exsimple/unix/exsimple ../exsimple/unix/exsimple.c -I/usr/local/include -I../../common -L../../demo -L/usr/local/lib -lsc_ex -lsc_da -DUNIX_64 -Wl,-rpath,../../demo -Wl,-rpath,'${ORIGIN}'

5.12 Oracle Solaris Compiling and Linking

Note:

These products do not support the "Solaris BSD" mode.

All libraries should be installed into a single directory. The libsc_ex.so, and libsc_da.so libraries must be linked with your application. It can be loaded when your application starts by linking them directly at compile time or they can be loaded dynamically by your application using library load functions (for example, dlopen).

To use Image Export annotation functions, you must link to libsc_ca.sl, requiring a separate license to Outside In Content Access or Search Export. Contact your Outside In sales representative for more information.

The shared libraries are dependent on the presence of the X libraries Xm, Xt and X11 if vector graphics support is required. It is the application developer's responsibility to ensure that the needed functions from these libraries are present before the product libraries are used.

The following is an example command line used to compile the sample application exsimple from the /sdk/samplecode directory. This command line is only an example. The actual command line required on the developer's system may vary. The example assumes that the include and library file search paths for the technology libraries and any required X libraries are set correctly. If they are not set correctly, the search paths for the include and/or library files must be explicitly specified via the -I include file path> and/or -L library file path options, respectively, so that the compiler and linker can locate all required files.

Developers may need to use the -xcc flag to allow C++ style comments.

5.12.1 Oracle Solaris SPARC

cc -w -o ../exsimple/unix/exsimple ../exsimple/unix/exsimple.c -I/usr/include -I/usr/dt/share/include -I../../common -L../../demo -L/usr/lib -L/lib -lsc_ex -lsc_da -Wl,-R,../../demo -Wl,-R,'${ORIGIN}'

Note: When running the 32-bit SPARC binaries on Solaris 9 systems, you may see the following error:

ld.so.1: simple: fatal: libm.so.1: version `SUNW_1.1.1' not found
(required by file ./libsc_vw.so)

This is due to a missing system patch. Please apply one of the following patches (or its successor) to your system to correct.

- For Solaris 9 - Patch 111722-04

5.12.2 Oracle Solaris x86

Note:

Your system will require Solaris patch 108436, which contains the C++ library libCstd.so.1.

cc -w -o ../exsimple/unix/exsimple ../exsimple/unix/exsimple.c -I/usr/include -I/usr/dt/share/include -I../../common -L../../demo -L/usr/lib -L/lib -lsc_ex -lsc_da -Wl,-R,../../demo -Wl,-R,'${ORIGIN}'

5.12.3 Oracle Solaris X Server Display Memory Issue

On some Solaris systems, the X Server does not free the memory for a display until the last close display call is made on that display. This problem is limited strictly to the Oracle Solaris OS and does not affect any other platforms, UNIX or otherwise. It also does not affect HTML Export when graphics conversions are turned off.

This problem is most noticeable when doing large amounts of graphics processing, when system memory usage can grow without bound. This memory can only be freed by shutting down the X Windows display the user pointed the technology to use via the DISPLAY environment variable. If that display is the "console" display, the user must log out of the console in order to free the memory. Users may be able to avoid this problem by choosing a display that they can close periodically.

6 Data Access Common Functions

The Data Access module is common to all Outside In technologies. It provides a way to open a generic handle to a source file. This handle can then be used in the functions described in this chapter.

This chapter includes the following sections:

- Section 6.1, "Deprecated Functions"

- Section 6.2, "DAInitEx"

- Section 6.3, "DADeInit"

- Section 6.4, "DAOpenDocument"

- Section 6.5, "DAOpenNextDocument"

- Section 6.6, "DACloseDocument"

- Section 6.7, "DARetrieveDocHandle"

- Section 6.8, "DASetOption"

- Section 6.9, "DAGetOption"

- Section 6.10, "DAGetFileId"

- Section 6.11, "DAGetFileIdEx"

- Section 6.12, "DAGetErrorString"

- Section 6.13, "DAGetTreeCount"

- Section 6.14, "DAGetTreeRecord"

- Section 6.15, "DAOpenTreeRecord"

- Section 6.16, "DASaveTreeRecord"

- Section 6.17, "DACloseTreeRecord"

- Section 6.18, "DASetStatCallback"

- Section 6.19, "DASetFileAccessCallback"

6.1 Deprecated Functions

DAInit and DaThreadInit have both been deprecated. DAInitEx now replaces these two functions. All new implementations should use DAInitEX, although the other two functions will continue to be supported.

6.2 DAInitEx

This function tells the Data Access module to perform any necessary initialization it needs to prepare for document access. This function must be called before the first time the application uses the module to retrieve data from any document. This function supersedes the old DAInit and DAThreadInit functions.

Note:

DAInitEx should only be called once per application, at application startup time. Any number of documents can be opened for access between calls to DAInitEx and DADeInit. If DAInitEx succeeds, DADeInit must be called regardless of any other API calls.

If the ThreadOption parameter is set to something other than DATHREAD_INIT_NOTHREADS, then this function's preparation includes setting up mutex function pointers to prevent threads from clashing in critical sections of the technology's code. The developer must actually code the threads after this function has been called. DAInitEx should be called only once per process and should be called before the developer's application begins the thread.

Note:

Multiple threads are supported for all Windows platforms, the 32-bit versions of Linux x86 and Solaris SPARC, Linux x64 and Solaris SPARC 64. Failed initialization of the threading function will not impair other API calls. If threading isn't initialized or fails, stub functions are called instead of mutex functions.

Prototype

DAERR DAInitEx(VTSHORT ThreadOption, VTDWORD dwFlags);

Parameters

- ThreadOption: can be one of the following values:

- DATHREAD_INIT_NOTHREADS: No thread support requested.

- DATHREAD_INIT_PTHREADS: Support for PTHREADS requested.

- DATHREAD_INIT_NATIVETHREADS: Support for native threading requested. Supported only on Microsoft Windows platforms and Oracle Solaris.

- dwFlags: can be one or more of the following flags OR-ed together

- OI_INIT_DEFAULT: Options Load and Save are performed normally

- OI_INIT_NOSAVEOPTIONS: The options file will not be saved on exit

- OI_INIT_NOLOADOPTIONS: The options file will not be read during initialization.

Return Values

- DAERR_OK: If the initialization was successful. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

6.3 DADeInit

This function tells the Data Access module that it will not be asked to read additional documents, so it should perform any cleanup tasks that may be necessary. This function should be called at application shutdown time, and only if the module was successfully initialized with a call to DAInitEx.

Prototype

DAERR DADeInit();

Return Values

- DAERR_OK: If the de-initialization was successful. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

6.4 DAOpenDocument

Opens a source file to make it accessible by one or more of the data access technologies. If DAOpenDocument succeeds, DACloseDocument must be called regardless of any other API calls.

For IO types other than IOTYPE_REDIRECT, the subdocument specification may be specified as part of the file's path. This is accomplished by appending a question mark delimiter to the path, followed by the subdocument specification. For example, to specify the third item within the file c:\docs\file.zip, specify the path c:\docs\file.zip?item.3 in the call to DAOpenDocument. DAOpenDocument always attempts to open the specification as a file first. In the unlikely event there is a file with the same name (including the question mark) as a file plus the subdocument specification, that file is opened instead of the archive item.

To take advantage of this feature when providing access to the input file using redirected IO, a subdocument specification must be provided via a response to an IOGetInfo message, IOGETINFO_SUBDOC_SPEC. To specify an item in an archive, first follow the standard redirected IO methods to provide a BASEIO pointer to the archive file itself. To specify an item within the archive, a redirected IO object must respond to the IOGETINFO_SUBDOC_SPEC message by copying to the supplied buffer the subdocument specification of the archive item to be opened. This message is received during the processing of DAOpenDocument.

Prototype

DAERR DAOpenDocument(
VTLPHDOC   lphDoc,
VTDWORD    dwSpecType,
VTLPVOID   pSpec,
VTDWORD    dwFlags);

Parameters

- lphDoc: Pointer to a handle that will be filled with a value uniquely identifying the document to data access. The developer uses this handle in subsequent calls to data access to identify this particular source file. This is not an operating system file handle.

- dwSpecType: Describes the contents of pSpec. Together, dwSpecType and pSpec describe the location of the source file.

Note:

The values used within IOTYPE_ARCHIVEOBJECT, IOTYPE_LINKEDOBJECT, and IOTYPE_OBJECT may change if different options are applied, with different versions of the technology, or after patches are applied.

Must be one of the following values:

- IOTYPE_ANSIPATH: Windows only. pSpec points to a NULL-terminated full path name using the ANSI character set and FAT 8.3 (Win16) or NTFS (Win32 and Win64) file name conventions.

- IOTYPE_UNICODEPATH: Windows only. pSpec points to a NULL-terminated full path name using the Unicode character set and NTFS (Win32 and Win64) file name conventions.

- IOTYPE_UNIXPATH: UNIX platforms only. pSpec points to a NULL-terminated full path name using the system default character set and UNIX path conventions. Unicode paths can be accessed on UNIX platforms by using a UTF-8 encoded path with IOTYPE_UNIXPATH.

- IOTYPE_REDIRECT: All platforms. pSpec points to a developer-defined struct that allows the developer to redirect the IO routines used to read the file. For more information, see Chapter 8, "Redirected IO."

- IOTYPE_ARCHIVEOBJECT: All platforms. Opens an embedded archive object for data access. pSpec points to a structure IOSPECARCHIVEOBJECT (for details, see Section 6.4.2, "IOSPECARCHIVEOBJECT Structure") that has been filled with values returned in a SCCCA_OBJECT content entry from Content Access.

- IOTYPE_LINKEDOBJECT: All platforms. Opens an object specified by a linked object for data access. pSpec points to a structure IOSPECLINKEDOBJECT (see Section 6.4.1, "IOSPECLINKEDOBJECT Structure") that has been filled with values returned in an SCCCA_BEGINTAG or SCCCA_ENDTAG with a subtype of SCCCA_LINKEDOBJECT content entry from Content Access.

- pSpec: File location specification.

- dwFlags: The low WORD is the file ID for the document (0 by default). If you set the file ID incorrectly, the technology fails. If set to 0, the file identification technology determines the input file type automatically. The high WORD should be set to 0.

Return Values

- DAERR_OK: Returned if the open was successful. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

6.4.1 IOSPECLINKEDOBJECT Structure

Structure used by DAOpenDocument.

Prototype

typedef struct IOSPECLINKEDOBJECTtag
{
VTDWORD    dwStructSize;
VTSYSPARAM hDoc;
VTDWORD    dwObjectId;  /* Object identifier. */
VTDWORD    dwType;      /* Linked Object type */

VTDWORD    dwParam2;    /* parameter for DoSpecial call */
VTDWORD    dwReserved1; /* Reserved. */
VTDWORD    dwReserved2; /* Reserved. */
} IOSPECLINKEDOBJECT,  * PIOSPECLINKEDOBJECT;

6.4.2 IOSPECARCHIVEOBJECT Structure

Structure used by DAOpenDocument.

Prototype

typedef struct IOSPECARCHIVEOBJECTtag
{
VTDWORD dwStructSize;
VTDWORD hDoc;        /* Parent Doc hDoc */
VTDWORD dwNodeId;    /* Node ID */
VTDWORD dwStreamId;
VTDWORD dwReserved1; /* Must always be 0 */
VTDWORD dwReserved2; /* Must always be 0 */
} IOSPECARCHIVEOBJECT,  * PIOSPECARCHIVEOBJECT;

6.5 DAOpenNextDocument

Allows an existing Export or Data Access document handle to be used or reused when opening a new document, enabling options to be preserved across multiple exports, or allowing multiple documents to be exported to the same output destination.

This function uses an existing "reference" handle as a starting point for opening another document. The reference handle may be either a document handle (obtained through DAOpenDocument) or an export handle (obtained via a call to EXOpenExport). The difference between using these two handle types is that certain document specification types (subdocuments of the original document) will not be successfully opened when a document handle is used as the reference handle. If an Export handle is used as the reference handle, subdocument specifications are allowed.

Since the same handle is used multiple times, only a single call to DACloseDocument is needed. Each document is actually closed when the next document is opened; successive calls to DAOpenNextDocument free the resources used in previous calls.

Using this function allows developers to make multiple calls to the EX functions, without having to re-set options every time. Options can be set once for the original document, and retained for each subsequent document.

Additionally, some export libraries allow exporting multiple source documents to a single output document. Currently, this is supported for PDF and multi-page TIFF output only. To do this, a developer would export the first document normally, then call DAOpenNextDocument to open the subsequent source documents, followed by a call to EXRunExport. EXOpenExport and EXCloseExport should only be called once each for this type of export.

Prototype

DAERR DAOpenNextDocument(
VTHANDLE hReference,
VTDWORD  dwSpecType,
VTLPVOID pSpec,
VTDWORD  dwFlags );

Parameters

- hReference: this VTHANDLE value may be either an hDoc, the VTHDOC document handle obtained through a prior call to DAOpenDocument; or an hExport, the VTHEXPORT handle obtained from a prior call to EXOpenExport. This is not an operating system file handle.

- dwSpecType: Describes the contents of pSpec. The dwSpecType values allowed by DAOpenDocument for this parameter are acceptable, with the exceptions that IOTYPE_ARCHIVEOBJECT and IOTYPE_LINKEDOBJECT are only allowed when hReference is an Export handle, obtained via a call to EXOpenExport.

- pSpec: File location specification.

- dwFlags: The low WORD is the file ID for the document (0 by default). If you set the file ID incorrectly, the technology fails. If set to 0, the file identification technology determines the input file type automatically. The high WORD should be set to 0.

Return Values

- DAERR_OK: Returned if the open was successful. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

- DAERR_FEATURENOTAVAIL: Returned if the value specified by dwSpecType is not one of the supported spec types for this operation.

6.6 DACloseDocument

This function is called to close a file opened by the reader that has not encountered a fatal error.

Prototype

DAERR DACloseDocument(
VTHDOC hDoc);

Parameters

- hDoc: Identifier of open document. Must be a handle returned by the DAOpenDocument function.

Return Value

- DAERR_OK: Returned if close succeeded. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

6.7 DARetrieveDocHandle

This function returns the document handle associated with any type of Data Access handle. This allows the developer to only keep the value of hItem, instead of both hItem and hDoc.

Prototype

DAERR DARetrieveDocHandle(
VTHDOC     hItem,
VTLPHDOC   phDoc);

Parameters

- hItem: Identifier of open document. May be the subhandle returned by the DAOpenDocument or DAOpenTreeRecord functions in the data access submodule. Passing in an hDoc created by DAOpenDocument for this parameter results in an error.

- phDoc: Pointer to a handle to be filled with the document handle associated with the passed subhandle.

Return Value

- DAERR_OK: Returned if the handle in phDoc is valid. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

6.8 DASetOption

This function is called to set the value of a data access option.

Prototype

DAERR DASetOption(
VTHDOC      hDoc,
VTDWORD     dwOptionId,
VTLPVOID    pValue,
VTDWORD     dwValueSize);

Parameters

- hDoc: Identifier of open document. May be a VTHDOC returned by the DAOpenDocument function, or the subhandle returned by the DAOpenDocument or DAOpenTreeRecord functions (VTHCONTENT, VTHTEXT, etc.). Setting an option for a VTHDOC affects all subhandles opened under it, while setting an option for a subhandle affects only that handle.
If this parameter is NULL, then setting the option affects all documents opened thereafter. Once an option is set using the NULL handle, this option becomes the default option thereafter. This parameter should only be set to NULL if the option being set can take that value.

- dwOptionId: The identifier of the option to be set.

- pValue: Pointer to a buffer containing the value of the option.

- dwValueSize: The size in bytes of the data pointed to by pValue. For a string value, the NULL terminator should be included when calculating dwValueSize.

Return Value

- DAERR_OK: Returned if DASetOption succeeded. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

6.9 DAGetOption

This function is called to retrieve the value of a data access option. The results of a call to this option are only valid if DASetOption has already been called on the option.

Prototype

DAERR DAGetOption(
VTHDOC    hItem,
VTDWORD   dwOptionId,
VTLPVOID  pValue,
VTLPDWORD pSize);

Parameters

- hItem: Identifier of open document. May be a VTHDOC returned by the DAOpenDocument function, or the subhandle returned by the DAOpenDocument or DAOpenTreeRecord functions (VTHCONTENT, VTHTEXT, etc.). Getting an option for a VTHDOC gets the value of that option for that handle, which may be different than the subhandle's value.

- dwOptionId: The identifier of the option to be returned.

- pValue: Pointer to a buffer containing the value of the option.

- pSize: This VTDWORD should be initialized by the caller to the size of the buffer pointed to by pValue. If this size is sufficient, the option value is copied into pValue and pSize is set to the actual size of the option value. If the size is not sufficient, pSize is set to the size of the buffer needed for the option and an error is returned.

Return Value

- DAERR_OK: Returned if DAGetOption was successful. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

6.10 DAGetFileId

This function allows the developer to retrieve the format of the file based on the technology's content-based file identification process. This can be used to make intelligent decisions about how to process the file and to give the user feedback about the format of the file they are working with.

Note: in cases where File ID returns a value of FI_UNKNOWN, then this function will apply the Fallback Format before returning a result.

Prototype

DAERR DAGetFileId(
VTHDOC      hDoc,
VTLPDWORD   pdwFileId);

Parameters

- hDoc: Identifier of open document. May be a VTHDOC returned by the DAOpenDocument function, a VTHEXPORT returned by the EXOpenExport function, or the subhandle returned by the DAOpenDocument or DAOpenTreeRecord functions (VTHEXPORT, VTHCONTENT, VTHTEXT, etc.).

- pdwFileId: Pointer to a DWORD that receives a file identification number for the file. These numbers are defined in sccfi.h.

Return Value

- DAERR_OK: Returned if DAGetFileId was successful. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

6.11 DAGetFileIdEx

This function allows the developer to retrieve the format of the file based on the technology's content-based file identification process. This can be used to make intelligent decisions about how to process the file and to give the user feedback about the format of the file they are working with. This function has all the functionality of DAGetFileID and adds the ability to return the raw FI value; in other words, the value returned by normal FI, without applying the FallbackFI setting.

Prototype

DAERR DAGetFileIdEx(
VTHDOC      hDoc,
VTLPDWORD   pdwFileId,
VTDWORD     dwFlags);

Parameters

- hDoc: Identifier of open document. May be a VTHDOC returned by the DAOpenDocument function, or the subhandle returned by the DAOpenDocument or DAOpenTreeRecord functions (VTHEXPORT, VTHCONTENT, VTHTEXT, etc.).

- pdwFileId: Pointer to a DWORD that receives a file identification number for the file. These numbers are defined in sccfi.h.

- dwFlags: DWORD that allows user to request specific behavior.

- DA_FILEINFO_RAWFI: This flag tells DAGetFileIdEx() to return the result of the File Identification operation before Extended File Ident. is performed and without applying the FallbackFI value.

Return Value

- DAERR_OK: Returned if DAGetFileIdEx was successful. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned. See the following tables for examples of expected output depending on the value of various options.

DAERR      deError,
VTLPVOID   pBuffer,
VTDWORD    dwBufSize);

Parameters

- Error: Error code passed in by the developer for which an error message is to be returned.

- pBuffer: This buffer is allocated by the caller and is filled in with the error message by this routine. The error message will be a NULL-terminated string.

- dwBufSize: Size of what pBuffer points to in bytes.

typedef struct SCCDATREENODEtag{
VTDWORD   dwSize;
VTDWORD   dwNode;
VTBYTE    szName[1024];
VTDWORD   dwFileSize;
VTDWORD   dwTime;

6.15 DAOpenTreeRecord

This function is called to open a record within an archive file and make it accessible by one or more of the data access technologies.

Search Export Only: Search Export's default behavior is to automatically open and process the contents of an archive. Use DAOpenTreeRecord and SCCOPT_XML_SEARCHML_FLAGS to change the default behavior if discrete processing of each document in an archive is desired.

DAERR DAOpenTreeRecord(
VTHDOC      hDoc,
VTLPHDOC    lphDoc,
VTDWORD     dwRecord);

lphDoc is not a file handle.

Parameters

- hDoc: Identifier of open document. May be a VTHDOC returned by the DAOpenDocument function, or the subhandle returned by the DAOpenDocument or DAOpenTreeRecord functions (VTHCONTENT, VTHTEXT, etc.).

- lphDoc: Pointer to a handle that is filled with a value uniquely identifying the document to data access. The developer uses this handle in subsequent calls to data access to identify this particular document.

- dwRecord: The record in the archive file to be opened.

Return Value

- DAERR_OK: Returned if DAOpenTreeRecord was successful. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

This function is called to extract a record in an archive file to disk.

DAERR DASaveTreeRecord(
VTHDOC      hDoc,
VTDWORD     dwRecord,
VTDWORD     dwSpecType,
VTLPVOID    pSpec,
VTDWORD     dwFlags);

Parameters

- hDoc: Handle that uniquely identifies the document to data access. This is not an operating system file handle.

- dwRecord: The record in the archive file to be extracted.

- dwSpecType: Describes the contents of pSpec. Together, dwSpecType and pSpec describe the location of the source file to which the file will be extracted. Must be one of the following values:

- IOTYPE_ANSIPATH: Windows only. pSpec points to a NULL-terminated full path name using the ANSI character set and FAT 8.3 (Win16) or NTFS (Win32 and Win64) filename conventions.

- IOTYPE_REDIRECT: Specifies that redirected I/O will be used to save the file.

- IOTYPE_UNICODEPATH: Windows only. pSpec points to a NULL-terminated full path name using the Unicode character set and NTFS (Win32 and Win64) file name conventions.

- IOTYPE_UNIXPATH: UNIX platforms only. pSpec points to a NULL-terminated full path name using the system default character set and UNIX path conventions. Unicode paths can be accessed on UNIX platforms by using a UTF-8 encoded path with IOTYPE_UNIXPATH.

- pSpec: File location specification. See the descriptions for individual dwSpecType values.

- dwFlags: Currently not used. Should be set to 0.

Return Values

- DAERR_OK: Returned if the save was successful. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

- DAERR_UNSUPPORTEDCOMP: Unsupported Compression Encountered.

Currently, only extracting a single file is supported. There is a known limitation where files in a Microsoft Binder file cannot be extracted.

6.17 DACloseTreeRecord

This function is called to close an open record file handle.

Search Export Only: Search Export's default behavior is to automatically open and process the contents of an archive. Use DACloseTreeRecord and SCCOPT_XML_SEARCHML_FLAGS to change the default behavior if discrete processing of each document in an archive is desired.

DAERR DACloseTreeRecord(
VTHDOC      hDoc);

Parameters

- hDoc: Identifier of open record document.

Return Value

- DAERR_OK: Returned if DACloseTreeRecord was successful. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

6.18 DASetStatCallback

This function sets up a callback that the technology periodically calls to verify the file is still being processed. The customer can use this with a monitoring process to help identify files that may be hung. Because this function is called more frequently than other callbacks, it is implemented separately.

Use of the Status Callback Function

An application's status callback function will be called periodically by Outside In to provide a status message. Currently, the only status message defined is OIT_STATUS_WORKING, which provides a "sign of life" that can be used during unusually long processing operations to verify that Outside In has not stopped working. If the application decides that it would not like to continue processing the current document, it may use the return value from this function to tell Outside In to abort.

The status callback function has two return values defined:

- OIT_STATUS_CONTINUE: Tells Outside In to continue processing the current document.

- OIT_STATUS_ABORT: Tells Outside In to stop processing the current document.

The following is an example of a minimal status callback function.

VTDWORD MyStatusCallback( VTHANDLE hUnique, VTDWORD dwID, VTSYSVAL
pCallbackData, VTSYSVAL pAppData)
{
if(dwID == OIT_STATUS_WORKING)
{
if( checkNeedToAbort( pAppData ) )
return (OIT_STATUS_ABORT);
}

return (OIT_STATUS_CONTINUE);
}

Prototype

DAERR DASetStatCallback(DASTATCALLBACKFN pCallback,
VTHANDLE hUnique,
VTLPVOID pAppData)

Parameters

- pCallback: Pointer to the callback function.

- hUnique: Handle that may either be an hDoc or an hExport.

- pAppData: User-defined data. Outside In never uses this value other than to provide it to the callback function.

The callback function should be of type DASTATCALLBACKFN. This function has the following signature:

(VTHANDLE hUnique, VTDWORD dwID, VTSYSVAL pCallbackData, VTSYSVAL pAppData)

- hUnique: Handle that may either be an hDoc or an hExport

- dwID: Handle that indicates the callback status.

- OIT_STATUS_WORKING

- OIT_STATUS_CONTINUE

- OIT_STATUS_CANCEL

- OIT_STATUS_ABORT

- pCallbackData: Currently always NULL

- pAppData: User-defined data provided to DASetStatCallback

Return Values

- DAERR_OK: If successful. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

6.19 DASetFileAccessCallback

This function sets up a callback that the technology will call into to request information required to open an input file. This information may be the password of the file or a support file location.

Use of the File Access Callback

When the technology encounters a file that requires additional information to access its contents, the application's callback function will be called for this information. Currently, only two different forms of information will be requested: the password of a document, or the file used by Lotus Notes to authenticate the user information.

The status callback function has two return values defined:

- SCCERR_OK: Tells Outside In that the requested information is provided.

- SCCERR_CANCEL: Tells Outside In that the requested information is not available.

This function will be repeatedly called if the information provided is not valid (such as the wrong password). It is the responsibility of the application to provide the correct information or return SCCERR_CANCEL.

Prototype

DAERR DASetFileAccessCallback (DAFILEACCESSCALLBACKFN pCallback);
VTHANDLE hUnique,
VTLPVOID pAppData)

Parameters

- pCallback: Pointer to the callback function.

Return Values

- DAERR_OK: If successful. Otherwise, one of the other DAERR_ values defined in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

The callback function should be of type DAFILEACCESSCALLBACKFN. This function has the following signature:

typedef VTDWORD (* DAFILEACCESSCALLBACKFN)(VTDWORD dwID, VTSYSVAL pRequestData, VTSYSVAL pReturnData, VTDWORD dwReturnDataSize);

- dwID – ID of information requested:

- OIT_FILEACCESS_PASSWORD – Requesting the password of the file

- OIT_FILEACCESS_NOTESID – Requesting the Notes ID file location

- pRequestData – Information about the file.

typedef struct {
VTDWORD   dwSize;           /* size of this structure */
VTWORD    wFIId;            /* FI id of reference file */
VTDWORD   dwSpecType;       /* file spec type */
VTVOID   *pSpec;            /* pointer to a file spec */
VTDWORD   dwRootSpecType;   /* root file spec type */
VTVOID   *pRootSpec;        /* pointer to the root file spec */
VTDWORD   dwAttemptNumber;  /* The number of times the callback has */
/* already been called for the currently */
/* requested item of information */
} IOREQUESTDATA, * PIOREQUESTDATA;

- pReturnData – Pointer to the buffer to hold the requested information – for OIT_FILEACCESS_PASSWORD and OIT_FILEACCESS_NOTESID, the buffer is an array of WORD characters.

- dwReturnDataSize – Size of the return buffer.

Note:

Not all formats that use passwords are supported. Only Microsoft Office binary (97-2003), Microsoft Office 2007, Microsoft Outlook PST 97-2013, Lotus NSF, PDF (with RC4 encryption), and Zip (with AES 128 & 256 bit, ZipCrypto) are currently supported.

Passwords for PST/OST files must be in the Windows single-byte character set. For example, Cyrillic characters should use the 1252 character set. For PST/OST files, Unicode password characters are not supported.

7 Export Functions

This chapter outlines the basic functions used to initiate the conversion of documents using the product API.

This chapter includes the following sections:

- Section 7.1, "General Functions"

- Section 7.2, "Annotation Functions"

7.1 General Functions

The following functions are general functions used in most products.

This section includes the following functions:

- Section 7.1.1, "EXOpenExport"

- Section 7.1.2, "EXCALLBACKPROC"

- Section 7.1.3, "EXCloseExport"

- Section 7.1.4, "EXRunExport"

- Section 7.1.5, "EXExportStatus"

7.1.1 EXOpenExport

This function is used to initiate the export process for a file that has been opened by DAOpenDocument. If EXOpenExport succeeds, EXCloseExport must be called regardless of any other API calls.

Note:

SCCOPT_GRAPHIC_TYPE = FI_NONE must be set (via DASetOption) before the call to EXOpenExport. Otherwise, the SCCUT_FILTEROPTIMIZEDFORTEXT speed enhancement for the PDF filter is not set. This will result in slower exports of PDFs when graphic output is not required.

Prototype

SCCERR EXOpenExport(
VTHDOC       hDoc,
VTDWORD      dwOutputId,
VTDWORD      dwSpecType,
VTLPVOID     pSpec,
VTDWORD      dwFlags,
VTSYSPARAM   dwReserved,
VTLPVOID     pCallbackFunc,
VTSYSPARAM   dwCallbackData,
VTLPHEXPORT  phExport);

phExport is not a file handle.

Parameters

- hDoc: A handle that identifies the source file, created by DAOpenDocument. Knowledge of this should only affect OEMs under the most unusual of circumstances.

- dwOutputId: File ID of the desired format of the output file. This value must be set to the following values:

- FI_GIF

- FI_JPEG2000

- FI_JPEGFIF

- FI_PNG

- FI_BMP

- FI_TIFF

- dwSpecType: Describes the contents of pSpec. Together, dwSpecType and pSpec describe the location of the initial output file. Must be one of the following values:

- IOTYPE_ANSIPATH: Windows only. pSpec points to a NULL-terminated full path name using the ANSI character set and FAT 8.3 (Win16) or NTFS (Win32 and Win64) file name conventions.

- IOTYPE_UNICODEPATH: Windows only. pSpec points to a NULL-terminated full path name using the Unicode character set and NTFS file name conventions.

Note:

If you are using IOTYPE_UNICODEPATH as a file spec type, if the calling application is providing an export callback function, you should set the option SCCOPT_EX_UNICODECALLBACKSTR to TRUE. Refer to the documentation on callbacks such as EX_CALLBACK_ID_CREATENEWFILE and the EXURLFILEIOCALLBACKDATAW structure for details

- IOTYPE_UNIXPATH: UNIX platforms only. pSpec points to a NULL-terminated full path name using the system default character set and UNIX path conventions. Unicode paths can be accessed on UNIX platforms by using a UTF-8 encoded path with IOTYPE_UNIXPATH.

- IOTYPE_REDIRECT: All platforms. pSpec may be NULL, and all file information specified in the callback routine. This allows the developer to redirect the IO routines used to write the files. For more information, see Chapter 8, "Redirected IO."

- pSpec: Initial output file location specification. This is either a pointer to a buffer or NULL. Usage differs depending on product:

- If the pointer is not NULL, the file referred to by the pSpec is assumed to be already open and the buffer's contents are based on the value of the dwSpecType parameter. See the descriptions for individual dwSpecType values in the preceding list.

- Passing NULL indicates the developer will use the EX_CALLBACK_ID_CREATENEWFILE callback to specify the initial output file instead of specifying it here. When this parameter is NULL, the developer must handle the EX_CALLBACK_ID_CREATENEWFILE callback or EXOpenExport returns an error.

- dwFlags: Must be set by developer to 0.

- dwReserved: Reserved. Must be set by developer to 0.

- pCallbackFunc: Pointer to a function of the type EXCALLBACKPROC. This function is used to give the developer control of certain aspects of the export process as they occur. For more details, see the definition for EXCALLBACKPROC in Section 7.1.2, "EXCALLBACKPROC." This parameter may be set to NULL if the developer does not wish to handle callbacks.

- dwCallbackData: This parameter is passed transparently to the function specified by pCallbackFunc. The developer may use this value for any purpose, including passing context information into the callback function.

- phExport: Pointer to a handle that receives a value uniquely identifying the document to the product routines. If the function fails, this value is set to VTHDOC_INVALID.

Return Values

- SCCERR_OK: If the open was successful. Otherwise, one of the other SCCERR_ values in sccerr.h is returned.

7.1.2 EXCALLBACKPROC

Type definition for the developer's callback function.

Prototype

DAERR (DA_ENTRYMODPTR EXCALLBACKPROC)(
VTHEXPORT    hExport,
VTSYSPARAM   dwCallbackData,
VTDWORD      dwCommandOrInfoId,
VTLPVOID     pCommandOrInfoData);

Parameters

- hExport: Export handle for the document. Must be a handle returned by the EXOpenExport function.

- dwCallbackData: This value is passed to EXOpenExport in the dwCallbackData parameter.

- dwCommandOrInfoId: Indicates the type of callback. For information about supported callbacks, see Chapter 9, "Callbacks."

- pCommandOrInfoData: Data associated with dwCommandOrInfoId. for information about supported callbacks, see Chapter 9, "Callbacks."

Return Values

- SCCERR_OK: Command was handled by the callback function.

- SCCERR_BADPARAM: One of the function parameters was invalid.

- SCCERR_NOTHANDLED: Callback function did not handle the command. This return value must be the default for all values of dwCommandOrInfoId the developer does not handle.

7.1.3 EXCloseExport

This function is called to terminate the export process for a file.

Prototype

SCCERR EXCloseExport(
VTHEXPORT   hExport);

Parameters

- hExport: Export handle for the document. Must be a handle returned by the EXOpenExport function.

Return Values

- SCCERR_OK: Returned if the close was successful. Otherwise, one of the other SCCERR_ values in sccerr.h is returned.

7.1.4 EXRunExport

This function is called to run the export process.

Prototype

SCCERR EXRunExport(
VTHEXPORT   hExport);

Parameters

- hExport: Export handle for the document. Must be a handle returned by the EXOpenExport function.

Return Values

- SCCERR_OK: Returned if the export was successful. Otherwise, one of the other SCCERR_ values in sccerr.h is returned.

7.1.5 EXExportStatus

This function is used to determine if there were conversion problems during an export. It returns a structure that describes areas of a conversion that may not have high fidelity with the original document.

Prototype

SCCERR EXExportStatus(VTHEXPORT hExport, VTDWORD dwStatusType, VTLPVOID pStatus)

Parameters

- hExport: Export handle for the document.

- dwStatusType: Specifies which status information should be filled in pStatus.

Return Values

SCCERR_OK: Returned if there were no problems. Otherwise, one of the other SCCERR_ values in sccerr.h is returned.

EXSUBDOCSTATUS Structure

The EXSUBDOCSTATUS structure is defined as follows:

typedef struct EXSUBDOCSTATUStag
{
VTDWORD dwSize;      /* size of this structure */
VTDWORD dwSucceeded; /* number of sub documents that were converted */
VTDWORD dwFailed;    /* number of sub documents that were not converted */
} EXSUBDOCSTATUS;

EXSTATUSINFORMATION Structure

The EXSTATUSINFORMATION structure is defined as follows:

typedef struct EXSTATUSINFORMATIONtag
{
VTDWORD dwVersion;              /* version of this structure, currently EXSTATUSVERSION1      */
VTBOOL bMissingMap;             /* a PDF text run was missing the toUnicode table */
VTBOOL bVerticalText;           /* a vertical text run was present */
VTBOOL bTextEffects;            /* unsupported text effects applied (i.e.Word Art)*/
VTBOOL bUnsupportedCompression; /* a graphic had an unsupported compression */
VTBOOL bUnsupportedColorSpace;  /* a graphic had an unsupported color space */
VTBOOL bForms;                  /* a sub documents had forms */
VTBOOL bRightToLeftTables;      /* a table had right to left columns */
VTBOOL bEquations;              /* a file had equations*/
VTBOOL bAliasedFont;            /* A font was missing, but a font alias was used */
VTBOOL bMissingFont;            /* The desired font wasn't present on the system */
VTBOOL bSubDocFailed;           /* a sub document was not converted */
} EXSTATUSINFORMATION;

#define EXSTATUSVERSION1 0X0001

Note:

When processing the main document, Search Export, HTML Export, and XML Export never use fonts, so bAliasedFont and bMissingFont will never report TRUE; however, when doing graphics conversions XML Export and HTML Export may use fonts, so bAliasedFont and bMissingFont may report TRUE.

7.2 Annotation Functions

Annotations are a way to highlight, insert, or delete text in product output, without modifying the original document. Examples of ways annotations can be used by developers include:

- highlighting search hits

- inserting notes to comment on text in the original document

- deleting sensitive information not intended for viewing

Other Outside In products are required to ascertain the proper character positions where the developer wishes to make annotations. Currently, only Content Access and the SearchML output format (available in Search Export) can be used to get these positions. Although the Content Access module is included with the product, license to use the Content Access API is not automatically granted with the purchase of the Export software.

A separate license for Content Access or Search Export is required to enable use of any of the annotation features that are supported by Image Export. Contact your Outside In sales representative for more information.

The following notes should be considered when using annotations:

- Processing annotations slow down the conversion process to some extent.

- While other products in the Outside In family support annotations, not all products support all types of annotations.

- The ACC acronym (Actual Character Count) is used in the following function descriptions. ACCs represent the location of text in the source document data stream. They represent a marker just before the location of text, and this marker is zero-based.
This is why startACC parameters should be set to an ACC value that represents the position just prior to the first character and endACC parameters should be set to an ACC value that represents the position just past the last character in the range. For this reason, users should make sure endACC values are 1 greater than the ACC of the last character in the desired range of annotation.

- Calling EXCloseExport causes all annotations set so far to be cleared.

This section includes the following functions:

- Section 7.2.1, "EXHiliteText"

- Section 7.2.2, "EXInsertText"

- Section 7.2.3, "EXHideText"

7.2.1 EXHiliteText

This function allows the developer to change foreground and background colors of a range of characters from the input document.

The colors set by this option can be overridden by the equivalent settings in the ExInsertText function.

Prototype

DAERR EXHiliteText(
VTHEXPORT           hExport,
PEXANNOHILITETEXT   pHiliteText);

Parameters

- hExport: Export handle for the document. Must be the handle returned by the EXOpenExport() function.

- pHiliteText: Pointer to a structure containing the information on what to highlight and how to highlight it.

Structure

A C data structure defined in sccex.h as follows:

typedef struct EXANNOHILITETEXTtag
{
VTDWORD         dwSize;
VTDWORD         dwStartACC;
VTDWORD         dwEndACC;     /* Last char to highlight +1 */
VTDWORD         dwOptions;
SCCVWCOLORREF   sForeground;
SCCVWCOLORREF   sBackground;
VTWORD          wCharAttr;
VTWORD          wCharAttrMask;
} EXANNOHILITETEXT;

- dwSize: Must be set by the developer to sizeof(EXANNOHILITETEXT).

- dwStartACC: The ACC of the first character to be highlighted.

- dwEndACC: ACC of the last character to be highlighted +1. Ranges for annotations have their end point set one past the ACC of the last character in the range. For example, to highlight a single character at ACC position 5, dwStartACC would be set to 5, and dwEndACC would be set to 5+1=6.

- dwOptions: Flags that provide highlight options. The default is all flags set to off. The valid flags are:

- SCCVW_USEFOREGROUND: Indicates that sForeground defines the foreground text color to apply to highlights.

- SCCVW_USEBACKGROUND: Indicates that sBackground defines the background text color to apply to highlights.

- SCCVW_USECHARATTR: Indicates that wCharAttr defines the character attributes to apply to highlights.

- sForeground: Defines the foreground text color to be used if the SCCVW_USEFOREGROUND flag is set in dwOptions. Set this value with the SCCANNORGB(red, green, blue) macro. The red, green and blue values are percentages of the color from 0-255 (with 255 being 100%). There is no default value for this parameter -- if it is set, the color must be specified.

- sBackground: Defines the background text color to be used if the SCCVW_USEBACKGROUND flag is set in dwOptions. Set this value with the SCCANNORGB(red, green, blue) macro. The red, green and blue values are percentages of the color from 0-255 (with 255 being 100%). There is no default value for this parameter. If it is set, the color must be specified.

- wCharAttr: Defines the character attributes to use if SCCVW_USECHARATTR is set in dwOptions. Only bits with the corresponding bits set in wCharAttrMask are affected. To turn off all character attributes, set this to SCCVW_CHARATTR_NORMAL (the default) and set wCharAttrMask to -1. Otherwise, set this to any of the following character attributes OR-ed together:

- SCCVW_CHARATTR_UNDERLINE

- SCCVW_CHARATTR_ITALIC

- SCCVW_CHARATTR_BOLD

- SCCVW_CHARATTR_STRIKEOUT

- SCCVW_CHARATTR_SMALLCAPS: Not supported.

- SCCVW_CHARATTR_OUTLINE: Not currently supported.

- SCCVW_CHARATTR_SHADOW: Not currently supported.

- SCCVW_CHARATTR_CAPS: Not currently supported.

- SCCVW_CHARATTR_SUBSCRIPT

- SCCVW_CHARATTR_SUPERSCRIPT

- SCCVW_CHARATTR_DUNDERLINE: Currently supported as single underline in Image Export.

- SCCVW_CHARATTR_WORDUNDERLINE

- SCCVW_CHARATTR_DOTUNDERLINE: Currently supported as single underline.

- wCharAttrMask: Defines which character attributes to change based on the settings of the bits in wCharAttr. Uses the same bit flags defined above for wCharAttr. Only attributes whose flag is set in this mask are modified to match the state specified by wCharAttr. This mask provides a way to distinguish between bits being set in wCharAttr because the developer wants to force a change to the character attributes and bits in wCharAttr that the developer would rather set to "inherit from the source document." The following are real-world examples of these interactions (all examples assume that SCCVW_USECHARATTR is set in dwOptions):

- Example 1: wCharAttr is set to SCCVW_CHARATTR_BOLD and wCharAttrMask is set to SCCVW_CHARATTR_BOLD. This results in bold being forced on in the annotation.

- Example 2: wCharAttr is set to SCCVW_CHARATTR_BOLD and wCharAttrMask is set to 0. This results in bold being left the way it was in the source document in the annotation.

- Example 3: wCharAttr is set to 0 and wCharAttrMask is set to SCCVW_CHARATTR_BOLD. This results in bold being forced off in the annotation.
The default value for this is 0, meaning that all the flags in wCharAttr are ignored.

Return Values

- DAERR_OK: Returned if the annotation was successfully added. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

7.2.2 EXInsertText

This function inserts a text string at a specified point in the document. The developer may also change character attributes or foreground or background colors. These settings override any provided by ExHiliteText.

Prototype

DAERR EXInsertText(
VTHEXPORT           hExport,
PEXANNOINSERTTEXT   pInsertText);

Parameters

- hExport: Export handle for the document. Must be the handle returned by the EXOpenExport() function.

- pInsertText: Pointer to a structure containing the information on the text to insert.

Structure

A C data structure defined in sccex.h as follows:

typedef struct EXANNOINSERTTEXTtag
{
VTDWORD         dwSize;
VTDWORD         dwTextACC;
VTLPWORD        pText;
VTDWORD         dwOptions;
SCCVWCOLORREF   sForeground;
SCCVWCOLORREF   sBackground;
VTWORD          wCharAttr;
VTWORD          wCharAttrMask;
} EXANNOINSERTTEXT;

- dwSize: Must be set by the OEM to sizeof(EXANNOINSERTTEXT).

- dwTextACC: Place to insert the string pointed to by pText. The string is inserted before the character normally at this ACC position. By default, the inserted string inherits the text attributes of the character at this position in the input document.

- pText: The text to be inserted. Specified as a Unicode string.

- dwOptions: This parameter sets flags that provide highlight options. The default is all flags off. The flags are:

- SCCVW_USEFOREGROUND: Indicates that sForeground defines the foreground text color to apply to highlights.

- SCCVW_USEBACKGROUND: Indicates that sBackground defines the background text color to apply to highlights.

- SCCVW_USECHARATTR: Indicates that wCharAttr defines the character attributes to apply to highlights.

- sForeground: Defines the foreground text color to be used if the SCCVW_USEFOREGROUND flag is set in dwOptions. Set this value with the SCCANNORGB(red, green, blue) macro. The red, green and blue values are percentages of the color from 0-255 (with 255 being 100%). There is no default value for this parameter -- if it is set, the color must be specified.

- sBackground: Defines the background text color to be used if the SCCVW_USEBACKGROUND flag is set in dwOptions. Set this value with the SCCANNORGB(red, green, blue) macro. The red, green and blue values are percentages of the color from 0-255 (with 255 being 100%). There is no default value for this parameter. If it is set, the color must be specified.

- wCharAttr: Defines the character attributes to use if SCCVW_USECHARATTR is set in dwOptions. Only bits with the corresponding bits set in wCharAttrMask are affected. To turn off all character attributes, set this to SCCVW_CHARATTR_NORMAL (the default) and set wCharAttrMask to -1. Otherwise, set this to any of the following character attributes OR-ed together:

- SCCVW_CHARATTR_UNDERLINE

- SCCVW_CHARATTR_ITALIC

- SCCVW_CHARATTR_BOLD

- SCCVW_CHARATTR_STRIKEOUT

- SCCVW_CHARATTR_SMALLCAPS: Not currently supported in Image Export.

- SCCVW_CHARATTR_OUTLINE: Not currently supported.

- SCCVW_CHARATTR_SHADOW: Not currently supported.

- SCCVW_CHARATTR_CAPS: Not currently supported.

- SCCVW_CHARATTR_SUBSCRIPT: SCCVW_CHARATTR_SUPERSCRIPT

- SCCVW_CHARATTR_DUNDERLINE: Currently supported as single underline.

- SCCVW_CHARATTR_WORDUNDERLINE: SCCVW_CHARATTR_DOTUNDERLINE

- wCharAttrMask: Defines which character attributes to change based on the settings of the bits in wCharAttr. Uses the same bit flags defined above for wCharAttr. Only attributes whose flag is set in this mask are modified to match the state specified by wCharAttr. This mask provides a way to distinguish between bits being set in wCharAttr because the developer wants to force a change to the character attributes, and bits in wCharAttr that the developer would rather set to "inherit from the source document."
The following are real-world examples of these interactions (all examples assume that SCCVW_USECHARATTR is set in dwOptions):

- Example 1: wCharAttr is set to SCCVW_CHARATTR_BOLD and wCharAttrMask is set to SCCVW_CHARATTR_BOLD. This results in bold being forced on in the annotation.

- Example 2: wCharAttr is set to SCCVW_CHARATTR_BOLD and wCharAttrMask is set to 0. This results in bold being left the way it was in the source document in the annotation.

- Example 3: wCharAttr is set to 0 and wCharAttrMask is set to SCCVW_CHARATTR_BOLD. This results in bold being forced off in the annotation.

The default value for this is 0, meaning that all the flags in wCharAttr are ignored.

Return Values

- DAERR_OK: The annotation was successfully added. Otherwise, one of the other DAERR_ values in sccda.h or one of the SCCERR_ values in sccerr.h is returned.

7.2.3 EXHideText

This function removes the selected range of characters in the input document from the output.

The hidden text does not appear in any form in the final converted document.

Prototype

SCCERR EXHideText(
VTHEXPORT         hExport,
PEXANNOHIDETEXT   pHideText)

Parameters

- hExportL Export handle for the document. Must be the handle returned by the EXOpenExport() function.

- dwStartACC: Position of the first character to be hidden.

- dwEndACC: Position of the last character to be hidden, plus one.

Return Values

- SCCERR_OK: Returned if the annotation was successfully added. Otherwise, one of the other SCCERR_* values in sccerr.h is returned.

8 Redirected IO

Anywhere a file specification (dwSpecType and pSpec parameters) is passed to a function in the product, the developer may use Redirected IO to completely take over responsibility for the low level IO calls of that particular file. The source file and all output files can be redirected in this way.

Redirected IO allows the developer great flexibility in the storage of, and access to, converted documents. For example, documents may be stored on file systems not supported natively by the software, or in a unique directory tree structure determined by the type of file.

This chapter includes the following sections:

- Section 8.1, "Using Redirected IO"

- Section 8.2, "Opening Files"

- Section 8.3, "IOClose"

- Section 8.4, "IORead"

- Section 8.5, "IOWrite"

- Section 8.6, "IOSeek"

- Section 8.7, "IOTell"

- Section 8.8, "IOGetInfo"

- Section 8.9, "IOSEEK64PROC / IOTELL64PROC"

8.1 Using Redirected IO

A developer can redirect the IO for an input or output file by providing a data structure that contains pointers to custom IO routines for reading and writing. This data structure is passed in place of a typical file specification. The developer must set the dwSpecType parameter of the DAOpenDocument call to IOTYPE_REDIRECT when the DAOpenDocument call is sent.

When dwSpecType is set this way, the pSpec element must contain a pointer to a developer-defined data structure that begins with a BASEIO structure (defined in baseIO.H). The BASEIO structure contains pointers to the basic IO functions for the IO system such as Read, Seek, Tell, etc. The developer must initialize these function pointers to their own functions that perform IO tasks. Beyond the BASEIO element, the developer may place any data he or she likes.

For instance, a developer's structure may be similar to the following:

typedef struct MYFILEtag
{
BASEIO    sBaseIO;       /* must be the first element */
VTDWORD   dwMyInfo1;
VTDWORD   dwMyInfo2;
.
.
.
} MYFILE;

Because the pSpec passed is essentially the "file handle" used by the software, the developer can redirect the IO on a file-by-file basis while still exporting "regular" disk-based files.

The BASEIO structure is defined as follows:

typedef struct BASEIOtag
{
IOCLOSEPROC pClose;
IOREADPROC pRead;
IOWRITEPROC pWrite;
IOSEEKPROC pSeek;
IOTELLPROC pTell;
IOGETINFOPROC pGetInfo;
IOOPENPROC pOpen; /* pOpen *MUST* be set to NULL. */
#ifndef NLM
IOSEEK64PROC pSeek64;
IOTELL64PROC pTell64;
#endif
VTVOID *aDummy[3];
} BASEIO, * PBASEIO;

The developer must implement the Close, Read, Write, Seek, Tell and GetInfo routines. The Open routine must be set to NULL. The first parameter to each of these routines is called hFile and is of the type HIOFILE. HIOFILE is simply the VTLPVOID to your data structure that was passed in the pSpec parameter of the DAOpenDocument call.

The sample source code for a simple implementation of Redirected IO is in the samples directory. This sample redirects the technology's IO through the fopen, fgetc, fseek, ftell and fclose run-time library routines.

Important:

Redirected IO does not cache the whole file. Seeks can occur throughout the file during the course of conversion. If the developer is implementing redirected IO on a slow or sequential link, it is the developer's responsibility to cache the file locally.

8.2 Opening Files

The developer does not see a call to pOpen when using redirected IO. When IOTYPE_REDIRECT is used, the structure passed in pSpec is defined to represent a file that is already open. The software can immediately call the pRead, pSeek, pTell and pWrite functions.

Files specified as using redirected IO must be open by the time they are handed off to the software.

8.3 IOClose

Closes the file identified by hFile and cleans up all memory associated with the file.

If you dynamically allocate your own file structures (MYFILE in the preceding discussion) it is required that the memory allocated be freed inside the call to IOClose or sometime thereafter.

Prototype

IOERR IOClose(
HIOFILE   hFile);

Parameters

- hFile: Identifies the file to be closed. Should be cast into a pointer to your data structure (MYFILE in the preceding discussion).

Return Values

- IOERR_OK: Close was successful.

- IOERR_UNKNOWN: Some error occurred on close.

8.4 IORead

Reads data from the current file position forward and resets the position to the byte after the last byte read.

Prototype

IOERR IORead(
HIOFILE         hFile,
VTBYTE        * pData,
VTDWORD         dwSize,
VTDWORD       * pCount);

Parameters

- hFile: Identifies the file to be read. Should be cast into a pointer to your data structure (MYFILE in the preceding discussion).

- pData: Points to the buffer into which the bytes should be read. Will be at least dwSize bytes big.

- dwSize: Number of bytes to read.

- pCount: Points to the number of bytes actually read by the function. This value is only valid if the return value is IOERR_OK.

Return Values

- IOERR_OK: Read was successful. pCount contains the number of bytes read and pData contains the bytes themselves.

- IOERR_EOF: Read failed because the file pointer was beyond the end of the file at the time of the read.

- IOERR_UNKNOWN: Read failed for some other reason.

8.5 IOWrite

Writes data from the current file position forward and resets the position to the byte after the last byte written.

Prototype

IOERR IOWrite(
HIOFILE         hFile,
VTBYTE       *  pData,
VTDWORD         dwSize,
VTDWORD       * pCount);

Parameters

- hFile: Identifies the file where the data is to be written. Should be cast into a pointer to your data structure (MYFILE in the preceding discussion).

- pData: Points to the buffer from which the bytes should be written. It must be at least dwSize bytes big. It is good practice to treat the data passed in by pData as "read only." This helps prevent unexpected behavior elsewhere in the system.

- dwSize: Number of bytes to write.

- pCount: Points to the number of bytes actually written by the function. This value is only valid if the return value is IOERR_OK.

Return Values

- IOERR_OK: Write was successful, pCount contains the number of bytes written.

- IOERR_UNKNOWN: Write failed for some reason.

8.6 IOSeek

Moves the current file position.

Prototype

IOERR IOSeek(
HIOFILE   hFile,
VTWORD    wFrom,
VTLONG    lOffset);

Parameters

- hFile: Identifies the file to be read. Should be cast into a pointer to your data structure (MYFILE in the preceding discussion).

- wFrom: One of the following values:

- IOSEEK_TOP: Move the file position lOffset bytes from the top (beginning) of the file.

- IOSEEK_BOTTOM: Move the file position lOffset bytes from the bottom (end) of the file.

- IOSEEK_CURRENT: Move the file position lOffset bytes from the current file position.

- lOffset: Number of bytes to move the file pointer. A positive value moves the file pointer forward in the file and a negative value moves it backward. If a requested seek value would move the file pointer before the beginning of the file, the file pointer should remain unchanged and IOERR_UNKNOWN should be returned. Seeking past EOF is allowed. In that case IOERR_OK should be returned. IOTell would return the requested seek position and IORead should return IOERR_EOF and 0 bytes read.

Return Values

- IOERR_OK: Seek was successful.

- IOERR_UNKNOWN: Seek failed for some reason.

8.7 IOTell

Returns the current file position.

Prototype

IOERR IOTell(
HIOFILE         hFile,
VTDWORD       * pOffset);

Parameters

- hFile: Identifies the file to be read. Should be cast into a pointer to your data structure (MYFILE in the preceding discussion).

- pOffset: Points to the current file position returned by the function.

Return Values

- IOERR_OK: Tell was successful.

- IOERR_UNKNOWN: Tell failed for some reason.

8.8 IOGetInfo

Returns information about an open file.

Prototype

IOERR IOGetInfo(
HIOFILE        hFile,
VTDWORD        dwInfoId,
VTVOID       * pInfo);

Parameters

- hFile: Identifies the file to be read. Should be cast into a pointer to your data structure (MYFILE in the previous discussion).

- dwInfoId: One of the following values:

- IOGETINFO_FILENAME: pInfo points to a string that should be filled with the base file name (no path) of the open file (for example TEST.DOC). If you do not know the file name, return IOERR_UNKNOWN. Certain file types (such as DataEase) must know the original file name in order to open secondary files required to correctly view the original file. If you return IOERR_UNKNOWN, these file types do not convert. For details, see Section 8.8.1, "IOGENSECONDARY and IOGENSECONDARYW Structures."

- IOGETINFO_PATHNAME: pInfo points to a string that should be filled with the fully qualified path name (including the file name) of the open file. For example, C:\MYDIR\TEST.DOC. If you do not know the path name, return IOERR_UNKNOWN.

- IOGETINFO_PATHTYPE: pInfo points to a DWORD that should be filled with the IOTYPE of the path returned by IOGETINFO_PATHNAME. For instance, if you return a DOS path name in the Unicode character set, you should return IOTYPE_UNICODEPATH. Even if redirected IO is in use, this should not be set to IOTYPE_REDIRECT. The value should reflect the style of path to be returned or any other values detailed in Section 7.1.1, "EXOpenExport.".

- IOGETINFO_ISOLE2STORAGE: Must return IOERR_FALSE. pInfo is not used.

- IOGETINFO_GENSECONDARY: pInfo points to a structure of type IOGENSECONDARY. Some file types require supporting files to be opened. These supporting files may contain formatting information or extra data. When using HTML Export, templates may link to other templates, and the paths to those templates must be resolved. Correct handling of IOGETINFO_GENSECONDARY is critical to the operation of the Outside In technology. For a list of these file types, see Section 8.8.2, "File Types That Cause IOGETINFO_GENSECONDARY."
Because the developer is in total control of the IO for the primary file, the technology does not know how to generate a path to these secondary files or even if the secondary files are accessible through the regular file system. The IOGETINFO_GENSECONDARY call gives the developer a chance to resolve this problem by generating a new IO specification for the secondary file in question. The developer gets just the base file name (often embedded in the original document or generated from the primary file's name) of the secondary file.

The developer may either use one of the standard Outside In IO types or totally redirect the IO for the secondary file, as well. For more details, see Section 8.8.1, "IOGENSECONDARY and IOGENSECONDARYW Structures.".

- IOGETINFO_SUBDOC_SPEC: This message should be handled only if the currently open file is an archive and a particular item within the archive is intended to be specified as the input file in a call to DAOpenDocument. In this case, pInfo points to a single-byte character string that should be filled with the subdocument specification of an item within the open file. For example, item.2 specifies item 2 within the archive file. When specifying a subdocument specification, return IOERR_OK. Any other return values cause the results of this message to be ignored.

- IOGETINFO_64BITIO: For redirected I/O that wishes to use 64-bit seek/tell functions, your IOGetInfo function must respond IOERR_TRUE to this dwInfoId. In addition, the pSeek64/pTell64 items in the baseio structure must be valid pointers to the proper function types.

- IOGETINFO_DPATHNAME: pInfo points to a structure of type DPATHNAME, which should be filled with the fully qualified path name (including the file name) of the open file, for example, C:\MYDIR\TEST.DOC. If you do not know the path name, return IOERR_UNKNOWN. The dwPathLen element contains the size of the buffer pointed to by the pPath element. If the buffer size is too small to contain the full path, modify dwPathLen to be the correct size of the buffer required to hold the path name in its IOTYPE character width including the NULL terminator and return IOERR_INSUFFICIENTBUFFER.
The following is a C data structure defined in SCCIO.H:

typedef struct DPATHNAMEtag
{
VTDWORD  dwPathLen;
VTVOID  *pPath;
} DPATHNAME, * PDPATHNAME;

Parameters

dwPathLen: Will be set to the number of bytes in the buffer pointed to by pPath. If the size of the buffer is insufficient, reset this element to the number of bytes required and return IOERR_INSUFFICIENTBUFFER.

pPath: Points to the buffer to be filled with the path name.

- IOGETINFO_GENSECONDARYDP: pInfo points to a structure of type IOGENSECONDARYDP. The dwSpecLen element contains the size of the buffer pointed to by the pSpec element. If the buffer size is too small to contain the spec, modify dwSpecLen to be the correct size of the buffer required to hold the path in its IOTYPE character width including the NULL terminator and return IOERR_INSUFFICIENTBUFFER.
The following is a C data structure defined in SCCIO.H:

typedef struct IOGENSECONDARYDPtag
{
VTDWORD         dwSize;
VTVOID *        pFileName;
VTDWORD         dwSpecType;
VTVOID *        pSpec;
VTDWORD         dwSpecLen;
VTDWORD         dwOpenFlags;
} IOGENSECONDARYDP, * PIOGENSECONDARYDP;

Parameters

dwSize: Will be set to sizeof (IOGENSECONDARYDP)

pFileName: A pointer to a string representing the file name of the secondary file that the technology requires. It is usually a name stored in the primary file (such as MYSTYLE.STY for a Word for DOS file) or a name generated from the primary file name. The primary file for a DataEase database has a .dba extension. The secondary name is the same file name but with a .dbm extension.

dwSpecType: The developer must fill this with the IOSPEC for the secondary file.

pSpec: On entry, this pointer points to an array of bytes or may be NULL (see dwSpecLen below). If the dwSpecType is set a regular IOTYPE such as IOTYPE_ANSIPATH, the developer may fill this array with the path name or structure required for that IOTYPE. If the developer is redirecting access to the secondary file, then dwSpecType will be IOTYPE_REDIRECT and the developer should replace pSpec with a pointer to a developer-defined structure that begins with the BASEIO structure (see Section 8.1, "Using Redirected IO").

The file is supposed to be opened by the OEM's redirected IO code by the time they return the BASEIO struct. This is because the pOpen routine in the BASEIO struct is supposed to be NULL.

dwSpecLen: On entry, this is set to the size of the pSpec buffer. If the size of the buffer is insufficient, replace the value with the number of bytes required and return IOERR_INSUFFICIENTBUFFER.

dwOpenFlags: Set by the technology. A set of bit flags describing how the secondary file should be opened. Multiple flags may be used by bitwise OR-ing them together. The following flags are currently used:

- IOOPEN_READ: The secondary file should be opened for read.

- IOOPEN_WRITE: The secondary file should be opened for write. If the specified file already exists, its contents are erased when this flag is set.

- IOOPEN_CREATE: The secondary file should be created (if it does not already exist) and opened for write.

Any other value should return IOERR_BADINFOID.

- pInfo: The size of the pInfo buffer depends on the dwInfoId selected. For IOGETINFO_FILENAME and IOGETINFO_PATHNAME, the buffer is of size MAX_PATH characters (each character is either one byte or two, depending on PATHTYPE). The IOGETINFO_PATHTYPE buffer is the size of a VTDWORD.

Return Values

- IOERR_OK: GetInfo was successful.

- IOERR_TRUE: Affirmative response from a true or false GetInfo.

- IOERR_FALSE: Negative response from a true or false GetInfo.

- IOERR_BADINFOID: dwInfoId can not be handled by this file type.

- IOERR_INVALIDSPEC: The file spec is bad for this type.

- IOERR_UNKNOWN: GetInfo failed for some other reason.

8.8.1 IOGENSECONDARY and IOGENSECONDARYW Structures

These structures are passed to the developer through the IOGetInfo function. They allow the developer to tell the technology where a secondary file, needed by the conversion process, is located.

The SpecType of the original file determines which of these two structures is used. If the SpecType is IOTYPE_UNICODEPATH, IOGENSECONDARYW is used. pFileName points to a Unicode string terminated with a NULL WORD. For all other SpecTypes, IOGENSECONDARY is used and pFileName points to a string terminated with a NULL BYTE.

When using HTML Export, consider the situation where the software must access a secondary template file. In that case, the SpecType of the original template specified by the option SCCOPT_EX_TEMPLATE determines which of the two structures is used.

The following is a C data structure defined in SCCIO.H:

typedef struct
{
VTDWORD     dwSize;
VTLPBYTE    pFileName;
VTDWORD     dwSpecType;
VTLPVOID    pSpec;
VTDWORD     dwOpenFlags
} IOGENSECONDARY, * PIOGENSECONDARY;

typedef struct
{
VTDWORD     dwSize;
VTLPWORD    pFileName;
VTDWORD     dwSpecType;
VTLPVOID    pSpec;
VTDWORD     dwOpenFlags
} IOGENSECONDARYW, * PIOGENSECONDARYW;

Parameters

- dwSize: Will be set to sizeof (IOGENSECONDARY) or sizeof (IOGENSECONDARYW) (both of these values are the same).

- pFileName: A pointer to a string representing the file name of the secondary file that the technology requires. It is usually a name stored in the primary file (such as MYSTYLE.STY for a Word for DOS file) or a name generated from the primary file name. The primary file for a DataEase database has a .dba extension. The secondary name is the same file name but with a .dbm extension.

- dwSpecType: The developer must fill this with the IOSPEC for the secondary file.

- pSpec: On entry, this pointer points to an array of 1024 bytes. If the dwSpecType is set a regular IOTYPE such as IOTYPE_ANSIPATH, the developer may fill this array with the path name or structure required for that IOTYPE. If the developer is redirecting access to the secondary file, then dwSpecType will be IOTYPE_REDIRECT and the developer should replace pSpec with a pointer to a developer-defined structure that begins with the BASEIO structure (see Section 8.1, "Using Redirected IO").
The file is supposed to be opened by the OEM's redirected IO code by the time they return the BASEIO struct. This is because the pOpen routine in the BASEIO struct is supposed to be NULL.

- dwOpenFlags: Set by the technology. A set of bit flags describing how the secondary file should be opened. Multiple flags may be used by bitwise OR-ing them together. The following flags are currently used:

- IOOPEN_READ: The secondary file should be opened for read.

- IOOPEN_WRITE: The secondary file should be opened for write. If the specified file already exists, its contents are erased when this flag is set.

- IOOPEN_CREATE: The secondary file should be created (if it does not already exist) and opened for write.

8.8.2 File Types That Cause IOGETINFO_GENSECONDARY

The following file types cause IOGETINFO_GENSECONDARY:

- Microsoft Word for DOS Versions 4, 5 and 6: Used to open and read the style sheet file associated with the document. The filter degrades if the style sheet is not present.

- Harvard Graphics DOS 3.x: Used to open and read the individual slides within ScreenShow and palette files. Files with the extension .ch3 are individual graphics or slides that can be opened using no secondary files. Files with the extension .sy3 are ScreenShows that reference a list of .ch3 files via the secondary file mechanism. There is also an optional palette file that can be referenced from a .ch3 file, but the filter degrades if the palette file is not present.

- R:Base: Used to open and read required schema file. The R:Base data files are named ????2.rbf but the data is useless without the schema file named ????1.rbf. There is also a ????3.rbf file associated with each database, but it is not used.

- Paradox 4.0 and Above: Used to open and read memo field data file. Paradox uses a separate file for all memo field data larger than 32 bytes.

- DataEase: Used to open and read the data file. DataEase databases include a .dba file that contains the schema (the file that the technology can identify as DataEase) and a .dbm file that contains the actual data.

- Templates (HTML Export): Any template that contains a {## link} will need to open the linked files. Additionally, when the root template is opened using redirected IO, each {## copy} macro in the template will result in a IOGETINFO_GENSECONDARY call, as well.

8.9 IOSEEK64PROC / IOTELL64PROC

These functions are for seek/tell using 64-bit offsets. These functions are not used by default. Rather, they are used if the IOGETINFO_64BITIO message returns IOERR_TRUE. This is so redirected I/O using strictly 32-bit I/O is unaffected.

8.9.1 IOSeek64

Moves the current file position.

Prototype

IOERR IOSeek64(
HIOFILE hFile,
VTWORD wFrom,
VTOFF_T offset);

Parameters

The parameter information is the same as for IOSeek(). However, the size of the VTOFF_T offset for IOSeek64() is 64-bit unlike the 32-bit offset in IOSeek().

8.9.2 IOTell64

Returns the current file position.

Prototype

IOERR IOTell64(
HIOFILE hFile,
VTOFF_T * pOffset);

Parameters

The parameter information is the same as for IOTell(). The only change is the use of a pointer to a 64-bit parameter for returning the offset.

9 Callbacks

Callbacks allow the developer to intervene at critical points in the export process. Read more about the callback procedure and the EXOpenExport function call in Section 7.1.1, "EXOpenExport." Each heading in this chapter is a possible value for the dwCommandOrInfoId parameter passed to the developer's callback.

The new SCCOPT_EX_CALLBACKS option allows developers to enable or disable some or all of these callbacks. See the Options documentation for details.

This section describes callbacks set in EXOpenExport. A second callback function, DASetStartCallback, can provide information about the progress of a file conversion. For more details, see Chapter 6, "Data Access Common Functions."

9.1 Callbacks Used In Image Export

The following information applies to Image Export.

This section describes the following callbacks:

- Section 9.1.1, "EX_CALLBACK_ID_CREATENEWFILE"

- Section 9.1.2, "EX_CALLBACK_ID_NEWFILEINFO"

- Section 9.1.3, "EX_CALLBACK_ID_PAGECOUNT"

9.1.1 EX_CALLBACK_ID_CREATENEWFILE

This callback is made any time a new output file needs to be generated. This gives the developer the chance to execute routines before each new file is created.

It allows the developer to override the standard naming for a file or to redirect entirely the IO calls for a file. This callback is made for all output files that are created.

If redirected IO is being used on output files, this callback must be implemented.

For this callback, the pCommandOrInfoData parameter points to a structure of type EXFILEIOCALLBACKDATA:

typedef struct EXFILEIOCALLBACKDATAtag
{
HIOFILE    hParentFile;
VTDWORD    dwParentOutputId;
VTDWORD    dwAssociation;
VTDWORD    dwOutputId;
VTDWORD    dwFlags;
VTDWORD    dwSpecType;
VTLPVOID   pSpec;
VTLPVOID   pExportData;
VTLPVOID   pTemplateName;
} EXFILEIOCALLBACKDATA;

- hParentFile: Handle to the initial output file with which the new file is associated. The dwAssociation describes the relationship. This handle is not intended for use by the developer. Set by caller.

- dwParentOutputId: Set by caller. The type of the parent file. This value is as used in the original ExOpenExport in the dwOutputId field. For example, for JPEG this value should be FI_JPEGFIF.

- dwAssociation: One of the following values:

- CU_ROOT: For the initial output file.

- CU_SIBLING: For new files that are not somehow owned by the parent file.

- dwOutputId: The type of the new file. This value should be the same as the value in dwParentOutputID.

- dwFlags: Reserved

- dwSpecType: IO specification type. For details about IO specifications, see Section 6.4, "DAOpenDocument."
This member in conjunction with pSpec allows the developer to select any location for the new file or even redirect its IO calls entirely. For more details, see Chapter 8, "Redirected IO." When the developer receives this callback, the value of this element is undefined. Must be set by developer if this callback returns SCCERR_OK.

- pSpec: This field holds the IO specification of the output file to be created. pSpec points to a buffer that is 1024 bytes in size. If your application needs to set the specification of the output file, it may do so by either writing new data into this buffer, or by changing the value of pSpec to point to memory owned by your application. If pSpec is set to a new value, then your application must ensure that this memory stays valid for an appropriate length of time, at least until the next callback message is received, or EXRunExport returns.
If the current export operation is using redirected IO, your application must create a redirected IO data structure for the new file and set pSpec to point to it. This pointer must stay valid until the structure's pClose function is called.

If your application sets dwSpecType to IOTYPE_UNICODEPATH, the specification must contain UCS-2 encoded Unicode characters.

When your application receives this callback, the contents of the buffer pointed to by pSpec are undefined. A specification must be defined by your application if this callback returns SCCERR_OK.

- pExportData: Pointer to data specific to the individual export. In this case, always a pointer to either an EXURLFILEIOCALLBACKDATA structure or an EXURLFILEIOCALLBACKDATAW structure. The EXURLFILEIOCALLBACKDATAW struct is only used when the SCCOPT_UNICODECALLBACKSTR option is set to TRUE. These two structures are defined in EXURLFILEIOCALLBACKDATA / EXURLFILEIOCALLBACKDATAW Structures. Set by caller.

- pTemplateName: NULL

9.1.1.1 EXURLFILEIOCALLBACKDATA / EXURLFILEIOCALLBACKDATAW Structures

The EXURLFILEIOCALLBACKDATA and EXURLFILEIOCALLBACKDATAW structures are defined as follows:

typedef struct EXURLFILEIOCALLBACKDATAtag
{
VTDWORD   dwSize;
VTBYTE    szURLString[VT_MAX_URL];
VTDWORD   dwFileID;
} EXURLFILEIOCALLBACKDATA;

typedef struct EXURLFILEIOCALLBACKDATAWtag
{
VTDWORD   dwSize;
VTWORD    wzURLString[VT_MAX_URL];
VTDWORD   dwFileID;
} EXURLFILEIOCALLBACKDATAW;

- dwSize: Set by Image Export to sizeof(EXURLFILEIOCALLBACKDATA) or sizeof(EXURLFILEIOCALLBACKDATAW).

- szURLString / wzURLString: This parameter can be set by the developer to a new URL that references the newly created file. This parameter is optional unless the pSpec provided by the developer points to something that cannot be used as a URL (as when using redirected IO, for example). In that case, this parameter must be set.
This string is written into any output file that needs to reference the newly created file, with appropriate conversions between single and double byte output. Because this parameter is a URL, it is assumed to be URL encoded. When used in conjunction with dwSpecType and pSpec, this parameter can be used to generate almost any structure or location for the output files, including things like writing the output files into a database and then using a CGI mechanism to retrieve them.

The current size limitation is 2048 characters. If the size exceeds this limit, the URL will be truncated and rendered useless.

- dwFileID: Set by the product. This is used as a unique identifier for each output file generated. It may be used for an OEM-specific purpose. When using HTML Export, this identifier is always set to zero when this callback is made as the result of a {## copy} statement in the template.

Return Value

- SCCERR_OK: dwSpecType, pSpec and szURLString (or wzURLString) have been populated with valid values.

- SCCERR_NOTHANDLED: Default naming should be used.

- SCCERR_FILEOPENFAILED: Some error was encountered creating a new output.

9.1.2 EX_CALLBACK_ID_NEWFILEINFO

This informational callback is made just after each new file has been created. Like the EX_CALLBACK_ID_CREATENEWFILE callback, the pExportData parameter points to an EXURLFILEIOCALLBACKDATA or an EXURLFILEIOCALLBACKDATW structure, but in this case the structure should be treated as read-only and the dwSpecType, pSpec and szURLString (or wzURLString) will be filled in.

This callback occurs for every new file. If the developer has used the EX_CALLBACK_ID_CREATENEWFILE notification to change the location of (or to set up redirected IO for) the new file, the data structure echoes back the information set by the developer during the EX_CALLBACK_ID_CREATENEWFILE callback.

Return Value

Must be either SCCERR_OK or SCCERR_NOTHANDLED. Return value is currently ignored.

9.1.3 EX_CALLBACK_ID_PAGECOUNT

Image Export uses this callback message to return a count of all of the output pages produced during an export operation. This count reflects the number of pages created by Outside In's processing of the input document; which in some cases may differ slightly from the number of pages as seen in the document's original application. The page count is not necessarily the same as the number of output files produced. For example, exporting to TIFF images will result in the same page count regardless of whether a single multi-page file was created or multiple individual TIFF files were created.

This callback occurs during the execution of EXRunExport.

10 Image Export Options

Options are parameters affecting the behavior of an export or transformation. These options are available to the developer when using Image Export. This chapter presents both the C/C++ and SOAP options relevant to the Image Export product.

While default values are provided, users are encouraged to set all options for a number of reasons. In some cases, the default values were chosen to provide backwards compatibility. In other cases, the default values were chosen arbitrarily from a range of possibilities.

One reason that users may want to avoid using the default value for an option is that the default value may change from one release to the next. This is because as standards evolve over time, defaults may be updated to reflect the current status of the technology.

10.1 Image Export C/C++ Options

Options are set using the DASetOption call. It is recommended that developers familiarize themselves with all of the options available.

Options may be Local, in which case they only affect the handle for which they are set, or Global, in which case they automatically affect all handles associated with the hDoc and must be set before the call to DAOpenDocument.

10.1.1 Character Mapping

This section discusses character mapping options.

10.1.1.1 SCCOPT_DEFAULTINPUTCHARSET

This option is used in cases where Outside In cannot determine the character set used to encode the text of an input file. When all other means of determining the file's character set are exhausted, Outside In will assume that an input document is encoded in the character set specified by this option. This is most often used when reading plain-text files, but may also be used when reading HTML or PDF files. The possible character sets are listed in charsets.h.

When "extended test for text" is enabled (see Section 10.1.3.2, "SCCOPT_FIFLAGS"), this option will still apply to plain-text input files that are not identified as EBCDIC or Unicode.

This option supersedes the SCCOPT_FALLBACKFORMAT option for selecting the character set assumed for plain-text files. For backwards compatibility, use of deprecated character-set -related values is still currently supported for SCCOPT_FALLBACKFORMAT, though internally such values will be translated into equivalent values for the SCCOPT_DEFAULTINPUTCHARSET. As a result, if an application were to set both options, the last such value set for either option will be the value that takes effect.

10.1.2 Output

This section discusses output options.

10.1.2.1 SCCOPT_RENDERING_PREFER_OIT

This option is valid on 32-bit Linux (Red Hat and Suse), Linux x86-64, Solaris Sparc, IBM AIX 32-bit, and HP-UX RISC 32-bit platforms.

When this option is set to TRUE, the technology will attempt to use its internal graphics code to render fonts and graphics. When set to FALSE, the technology will render images using the operating system's native graphics subsystem (X11 on UNIX/Linux platforms). This requires that there be an X11 display and a valid DISPLAY variable, regardless of the type of input document.

It is important for the system to be able to locate usable fonts when this option is set to TRUE. Only TrueType fonts (*.ttf or *.ttc files) are currently supported. To ensure that the system can find them, make sure that the environment variable GDFONTPATH includes one or more paths to these files. If the variable GDFONTPATH can't be found, the current directory is used. If fonts are called for and cannot be found, Image Export will exit with an error. Oracle does not provide fonts with any Outside In product.

Note:

Note that the maximum total path size for paths included in GDFONTPATH is 256 characters - paths longer than this will be truncated and will result in fonts not being discovered by Image Export.

Handle Types

One of the following values:

- TRUE: Use the technology's internal graphics rendering code to produce bitmap output files whenever possible.

- FALSE: Use the operating system's native graphics subsystem.

Default

FALSE

10.1.3 Input Handling

This section discusses input handling options.

10.1.3.1 SCCOPT_FALLBACKFORMAT

This option controls how files are handled when their specific application type cannot be determined. This normally affects all plain-text files, because plain-text files are generally identified by process of elimination, for example, when a file isn't identified as having been created by a known application, it is treated as a plain-text file.

It is recommended that FI_NONE be set to prevent Image Export from exporting unidentified binary files as though they were text, which could generate many pages of "garbage" output.

This option must be set for an hDoc before any subhandle has been created for that hDoc.

A number of values that were formerly allowed for this option have been deprecated. Specifically, the values that selected specific plain-text character sets are no longer to be used. Instead, applications should use the SCCOPT_DEFAULTINPUTCHARSET option for such functionality.

Handle Types

NULL, VTHDOC

Scope

Global

Data Type

VTDWORD

Data

The high VTWORD of this value is reserved and should be set to 0, and the low VTWORD must have one of the following values:

- FI_TEXT: Unidentified file types will be treated as text files.

- FI_NONE: Outside In will not attempt to process files whose type cannot be identified. This will include text files. When this option is selected, an attempt to process a file of unidentified type will cause Outside In to return an error value of DAERR_FILTERNOTAVAIL (or SCCERR_NOFILTER).

Default

- FI_TEXT

10.1.3.2 SCCOPT_FIFLAGS

This option affects how an input file's internal format (application type) is identified when the file is first opened by the Outside In technology. When the extended test flag is in effect, and an input file is identified as being either 7-bit ASCII, EBCDIC, or Unicode, the file's contents will be interpreted as such by the export process.

The extended test is optional because it requires extra processing and cannot guarantee complete accuracy (which would require the inspection of every single byte in a file to eliminate false positives.)

Handle Types

Default

- SCCUT_FI_EXTENDEDTEST: The technology will attempt an extra test after the file is first opened to see if it is 7-bit text or EBCDIC.

10.1.3.5 SCCOPT_PDF_FILTER_REORDER_BIDI

This option controls whether or not the PDF filter will attempt to reorder bidirectional text runs so that the output is in standard logical order as used by the Unicode 2.0 and later specification. This additional processing will result in slower filter performance according to the amount of bidirectional data in the file.

10.1.3.6 SCCOPT_TIMEZONE

This option allows the user to define an offset to GMT that will be applied during date formatting, allowing date values to be displayed in a selectable time zone. This option affects the formatting of numbers that have been defined as date values. This option will not affect dates that are stored as text.

Note:

- SCCOPT_FLAGS_ALLISODATETIMES: When this flag is set, all Date and Time values are converted to the ISO 8601 standard. This conversion can only be performed using dates that are stored as numeric data within the original file.

- SCCOPT_FLAGS_STRICTFILEACCESS: When an embedded file or URL can't be opened with the full path, OIT will sometimes try and open the referenced file from other locations, including the current directory. When this flag is set, it will prevent OIT from trying to open the file from any location other than the fully qualified path or URL.

Default

0: All flags turned off

10.1.3.8 SCCOPT_IGNORE_PASSWORD

This option can disable the password verification of files where the contents can be processed without validation of the password. If this option is not set, the filter should prompt for a password if it handles password-protected files.

10.1.4 Compression

This section describes compression options.

10.1.4.1 SCCOPT_FILTERJPG

This option can disable access to any files using JPEG compression, such as JPG graphic files or TIFF files using JPEG compression, or files with embedded JPEG graphics. Attempts to read or write such files when this option is enabled will fail and return the error SCCERR_UNSUPPORTEDCOMPRESSION if the entire file is JPEG compressed, and grey boxes for embedded JPEG-compressed graphics.

The following is a list of file types affected when this option is disabled:

- JPG files

10.1.4.2 SCCOPT_FILTERLZW

This option can disable access to any files using Lempel-Ziv-Welch (LZW) compression, such as .GIF files, .ZIP files or self-extracting archive (.EXE) files containing "shrunk" files. Attempts to read or write such files when this option is enabled will fail and return the error SCCERR_UNSUPPORTEDCOMPRESSION if the entire file is LZW compressed, and grey boxes for embedded LZW-compressed graphics.

The following is a list of file types affected when this option is disabled:

- GIF files

- TIF files using LZW compression (note that TIF files will still be created when LZW compression is used and this option is enabled, but the resulting images will be large, uncompressed TIF files)

- PDF files that use internal LZW compression

- ZIP and self-extracting archive (.EXE) files containing "shrunk" files

- Postscript files using LZW compression

Image Export will not be affected by this option when processing formats that compress subfile contents but not subfile names, such as TAR and ZIP.

Although this option can disable access to files in ZIP or EXE archives stored using LZW compression, any files in such archives that were stored using any other form of compression will still be accessible.

The setting for this option overrides the requested output graphic format when there is a conflict.

10.1.5 Graphics

This section discusses graphics options.

10.1.5.1 SCCOPT_GIF_INTERLACED

This option allows the developer to specify interlaced or non-interlaced GIF output. Interlaced GIFs are useful when graphics are to be downloaded over slow Internet connections. They allow the browser to begin to render a low-resolution view of the graphic quickly and then increase the quality of the image as it is received. There is no real penalty for using interlaced graphics.

This option is only valid if the dwOutputID parameter of the EXOpenExport function is set to FI_GIF.

10.1.5.2 SCCOPT_GRAPHIC_CROPPING

When set to SCCGRAPHIC_CROPTOCONTENT, this option forces Image Export to crop whitespace from the edge of each output image. This includes margins and any unused space at the end of a page. This results in smaller output files without any loss of original input document content.

If there is no content, then no cropping is performed.

Handle Types

10.1.5.3 SCCOPT_GRAPHIC_HEIGHT

This option defines the absolute height in pixels to which exported graphics will be resized. If this option is set and the SCCOPT_GRAPHIC_WIDTH option is not, the width of the image will be calculated based on the aspect ratio of the source image. The developer should be aware that very large values for this option or SCCOPT_GRAPHIC_WIDTH could produce images whose size exceeds available system memory, resulting in conversion failure.

If you are exporting a non-graphic file (word processing, spreadsheet or archive) and the settings for SCCOPT_GRAPHIC_HEIGHT and SCCOPT_GRAPHIC_WIDTH do not match the aspect ratio of the original document, the exported image will have whitespace added so that the original file's aspect ratio is maintained.

The settings for the SCCOPT_GRAPHIC_HEIGHTLIMIT and SCCOPT_GRAPHIC_WIDTH options can override the setting for SCCOPT_GRAPHIC_HEIGHT.

- 0: No absolute height specified.

10.1.5.4 SCCOPT_GRAPHIC_HEIGHTLIMIT

Note that this option differs from the behavior of setting the height of graphics in that it sets an upper limit on the image height. Images larger than this limit will be reduced to the limit value. However, images smaller than this height will not be enlarged when using this option. Setting the height using SCCOPT_GRAPHIC_HEIGHT causes all output images to be reduced or enlarged to be of the specified height.

The maximum height of the output graphic in pixels. A value of zero is equivalent to SCCGRAPHIC_NOLIMIT, which causes this option to be ignored.

Default

- SCCGRAPHIC_NOLIMIT: No absolute height limit specified.

10.1.5.5 SCCOPT_GRAPHIC_OUTPUTDPI

This option allows the user to specify the output graphics device's resolution in DPI and only applies to images whose size is specified in physical units (in/cm). For example, consider a 1" square, 100 DPI graphic that is to be rendered on a 50 DPI device (SCCOPT_GRAPHIC_OUTPUTDPI is set to 50). In this case, the size of the resulting TIFF, BMP, JPEG, GIF, or PNG will be 50 x 50 pixels.

In addition, the special #define of SCCGRAPHIC_MAINTAIN_IMAGE_DPI, which is defined as 0, can be used to suppress any dimensional changes to an image. In other words, a 1" square, 100 DPI graphic will be converted to an image that is 100 x 100 pixels in size. This value indicates that the DPI of the output device is not important. It extracts the maximum resolution from the input image with the smallest exported image size.

Setting this option to SCCGRAPHIC_MAINTAIN_IMAGE_DPI may result in the creation of extremely large images. Be aware that there may be limitations in the system running this technology that could result in undesirably large bandwidth consumption or an error message. Additionally, an out of memory error message will be generated if system memory is insufficient to handle a particularly large image.

Also note that the SCCGRAPHIC_MAINTAIN_IMAGE_DPI setting will force the technology to use the DPI settings already present in raster images, but will use the current screen resolution as the DPI setting for any other type of input file.

For some output graphic types, there may be a discrepancy between the value set by this option and the DPI value reported by some graphics applications. The discrepancy occurs when the output format uses metric units (DPM, or dots per meter) instead of English units (DPI, or dots per inch). Depending on how the graphics application performs rounding on meters to inches conversions, the DPI value reported may be 1 unit more than expected. An example of a format which may exhibit this problem is PNG.

10.1.5.6 SCCOPT_GRAPHIC_SIZELIMIT

This option is used to set the maximum size of the exported graphic in pixels. It may be used to prevent inordinately large graphics from being converted to equally cumbersome output files, thus preventing bandwidth waste.

SCCOPT_GRAPHIC_SIZELIMIT takes precedence over all other options and settings that affect the size of a converted graphic.

10.1.5.7 SCCOPT_GRAPHIC_SIZEMETHOD

This option determines the method used to size graphics. The developer can choose among three methods, each of which involves some degree of trade off between the quality of the resulting image and speed of conversion.

Using the quick sizing option results in the fastest conversion of color graphics, though the quality of the converted graphic will be somewhat degraded. The smooth sizing option results in a more accurate representation of the original graphic, as it uses anti-aliasing. Antialiased images may appear smoother and can be easier to read, but rendering when this option is set will require additional processing time. The grayscale only option also uses antialiasing, but only for grayscale graphics, and the quick sizing option for any color graphics.

The smooth sizing option does not work on images which have a width or height of more than 4096 pixels.

Default

SCCGRAPHIC_SMOOTHSIZING

10.1.5.8 SCCOPT_GRAPHIC_TRANSPARENCYCOLOR

This option allows the user to set the color used as the "transparency color" in the output graphic file. Naturally, this option is only used when the selected output graphic file format supports transparency (GIF and PNG only). If the option is not set, the default behavior is to use the same color value that the input file used as the transparency color.

Use the SCCVWRGB(r, g, b) macro to create the color value to pass to this option. The red, green and blue values are percentages of the color from 0-255 (with 255 being 100%). Note that this macro should be used to set a variable of type SCCVWCOLORREF and that variable should then be passed to the set option routine (instead of trying to use the macro as part of the set option call directly).

Since there is no way to "unset" an option once it has been set, the developer may set the option to SCCGRAPHIC_DEFAULTTRANSPARENCYCOLOR if they wish to revert to the default behavior.

10.1.5.9 SCCOPT_GRAPHIC_WIDTH

This option defines the absolute width in pixels to which exported graphics will be resized. If this option is set and the SCCOPT_GRAPHIC_HEIGHT option is not, the height of the image will be calculated based on the aspect ratio of the source image. The developer should be aware that very large values for this option or SCCOPT_GRAPHIC_HEIGHT could produce images whose size exceeds available system memory, resulting in conversion failure.

If you are exporting a non-graphic file (word processing, spreadsheet or archive) and the settings for SCCOPT_GRAPHIC_HEIGHT and SCCOPT_GRAPHIC_WIDTH do not match the aspect ratio of the original document, the exported image will have whitespace added so that the original file's aspect ratio is maintained.

It should be noted that regardless whether the SCCOPT_GRAPHIC_HEIGHTLIMIT option is set or not, any resized images will preserve their original aspect ratio.

Note that this option differs from the behavior of setting the width of graphics by using SCCOPT_GRAPHIC_WIDTH in that it sets an upper limit on the image width. Images larger than this limit will be reduced to the limit value. However, images smaller than this width will not be enlarged when using this option.

10.1.5.11 SCCOPT_GRAPHIC_RENDERASPAGE

SCCOPT_GRAPHIC_RENDERASPAGE affects the way raster (bitmapped) images such as TIFF, JPG, and PNG are handled. The default behavior for Image Export is to export such images as copies of the input document, scaled according to the width and height options set by the caller. If SCCOPT_GRAPHIC_RENDERASPAGE is enabled, the output produced by Image Export will look like a printed page, with the image placed on a white rectangle representing a "virtual page." As usual, the dimensions of the entire image, including the virtual page, will be controlled by the normal Image Export output width and height settings. The margins into which the image will be placed will be controlled by existing Outside In print margin options. The image itself will be attempted to be scaled to its true (physical) size, or scaled down to fit within the margins if necessary.

10.1.6.4 SCCOPT_MAXSSDBPAGEHEIGHT

Normally, the size of images generated from spreadsheet worksheets and database tables is limited to the size of the page defined by the input document's page size information and how the SCCOPT_USEDOCPAGESETTINGS, SCCOPT_GRAPHIC_WIDTH and SCCOPT_GRAPHIC_HEIGHT options are set. If, after scaling is factored in, the resulting image is too large to fit on a single page, it is split up into multiple pages.

The SCCOPT_MAXSSDBPAGEWIDTH and SCCOPT_MAXSSDBPAGEHEIGHT options are used to change the size of a page to match the scaled size of the page being rendered - within limits. The key reason for those limits is that rendering very large pages can easily overwhelm the memory available on the system. When using this feature, a calculation should be made to be sure that the values passed in work within said memory limits. The values for these two options will override the current page dimensions if necessary.

The memory needed may be calculated based on the following:

memory = [max. worksheet/table height (in inches)]  x  [max. worksheet/table width (in inches)]  x  [dpi setting]2  x  3 bytes/pixel  +  a bit extra for the needs of the rest of the conversion

By default, these options are set to the current page dimensions. Users may choose to set only one of the two options if desired. If, for example, only the SCCOPT_MAXSSDBPAGEWIDTH is set, then the height of the page will be based on the normal page height.

When a worksheet or table is larger than the maximum values specified by these options, then the file is rendered on multiple pages, with the requested (larger) page dimensions.

These new options grow the page size (if needed) to match the size of the worksheet or table. This differs from the SCCOPT_GRAPHIC_WIDTH and SCCOPT_GRAPHIC_HEIGHT options, which set an absolute page size without regard to the size of the worksheet or table.

If text in cells ends up extending past the edge of the cell and beyond the edge of the page, Image Export writes one or more additional pages for the overflow text.

- SCCVW_DATEORDER_YMD: Year, Month, Date

- wShortDateYearDigits: This parameter is specific to the SCCVWNUMBERFORMAT structure. This is the number of digits in the year as specified by the Windows registry entry sShortDate. This option only works on variable formats. For example, only one of the several date formats in Microsoft Excel is variable.

- wShortDateMonthDigits: This parameter is specific to the SCCVWNUMBERFORMAT structure. This is the number of digits in the month as specified by the Windows registry entry sShortDate.

- wShortDateDayDigits: This parameter is specific to the SCCVWNUMBERFORMAT structure. This is the number of digits in the day as specified by the Windows registry entry sShortDate.

- wShortDateFlags: This parameter is specific to the SCCVWNUMBERFORMAT structure. It is reserved for internal use.

10.1.7.7 SCCOPT_WPEMAILHEADEROUTPUT

The former option SCCOPT_WPMIMEHEADEROUTPUT has been deprecated. This option controls rendering of email headers.

Scope

Global

Data Type

VTDWORD

Data

One of these values:

- SCCUT_WP_EMAILHEADERSTANDARD: Displays "To," "From," "Subject," "CC," "BCC," "Date Sent," and "Attachments" header fields only. The filter outputs any fields not listed above as hidden fields, so they will not display.

- SCCUT_WP_EMAILHEADERNONE: Displays no email header fields.

- SCCUT_WP_EMAILHEADERALL: Displays all available email headers.

Default

SCCUT_WP_EMAILHEADERSTANDARD

10.1.7.8 SCCOPT_MAILHEADERVISIBLE

Along with SCCOPT_MAILHEADERHIDDEN, these options exist to allow the developer fine-grained control over what email headers are rendered. These options modify which email headers are displayed, and are based on the most recent setting of SCCOPT_WPEMAILHEADEROUTPUT. To implement a fully customized set of email headers for display, your code should first set the SCCOPT_WPEMAILHEADEROUTPUT option to select a baseline set of headers, then use these options to selectively add or remove headers from that set.

Setting a header to be visible means that it will be rendered when that header is found in a document of the appropriate type. Selected headers that are not present in the input file will not have any corresponding output created for them (no 'empty' headers will be created). Setting a header to be hidden means that it will not be rendered for the document types specified.

SCCUTEMAILHEADERINFO structure

SCCUTEMAILHEADERINFO structure

This structure is used by the SCCOPT_WPMAILHEADERVISIBLE/SCCOPT_WPMAILHEADERHIDDEN options to specify the headers to show or hide.

typedef struct SCCUTEMAILHEADERINFOtag
{
VTDWORD    dwHeaderID;
VTDWORD    dwSubtypeID;
VTWORD     wsMimeHeaderName[SCCUT_MAIL_NAMELENGTH];
VTWORD     wsMimeHeaderLabel[SCCUT_MAIL_NAMELENGTH];
} SCCUTEMAILHEADERINFO, *PSCCUTEMAILHEADERINFO;

Parameters:

- dwHeaderID
Either the ID of a predefined email header field, found in sccca.h (for example SCCCA_MAIL_TO), or an identifier between NONSTANDARD_HEADER_ID_BASE and NONSTANDARD_HEADER_ID_TOP for tracking a user-defined header.

- dwSubTypeID
The type(s) of documents in which to either show or hide this header. These can be joined with a bitwise OR operator. Available subtypes are:

- SCCUT_MAILTYPE_EMAIL

- SCCUT_MAILTYPE_JOURNAL

- SCCUT_MAILTYPE_CONTACT

- SCCUT_MAILTYPE_NOTE

- SCCUT_MAILTYPE_APPOINTMENT

- SCCUT_MAILTYPE_TASK

- SCCUT_MAILTYPE_POST

- SCCUT_MAILTYPE_DISTROLIST

- wsMimeHeaderName
A Unicode string containing the value of a user-specified MIME header name. This value is only used when the dwHeaderId field contains a user-defined ID value between NONSTANDARD_HEADER_ID_BASE and NONSTANDARD_HEADER_ID_TOP.

- wsMimeHeaderLabel
Unicode string that will be used as the label for a user-defined MIME header. This value is only used for user-defined headers.

Note:

Support for user-defined MIME headers is intended to allow Outside In to selectively display MIME headers that are not included in the predefined set of email headers known to Outside In. It is likely that most developers using Outside In will not need to specify user-defined MIME headers. Knowledge of the particular MIME headers present in the input email files is necessary in order to take advantage of this capability.

SCCVWFONTSPEC Structure

10.1.8.1.1 SCCVWFONTSPEC Structure

This structure is used by various options to specify a font.

SCCVWFONTSPEC is a C data structure defined in sccvw.h as follows:

typedef struct
{
VTTCHAR  szFace[40];
VTWORD   wHeight;
VTWORD   wAttr;
VTWORD   wType;
} SCCVWFONTSPEC,  * LPSCCVWFONTSPEC;

Parameters

- szFace: The name of the font. For example, "Helvetica Compressed." The default is "Arial", however this default is constrained by the fonts available on the system.

- wHeight: Size of the font in half points. For example, a value of 24 will produce a 12-point font. This size is only applied when the font size is not known. The default is 10-point, however this default is constrained by the font sizes available on the system.

- wAttr: The attributes of the font. This parameter is used primarily by the Outside In Viewer Technology and is currently ignored by ImageExport.

- wType: Should be set to 0.

typedef struct SCCVWFONTALIAStag
{
VTDWORD dwSize;
VTDWORD dwAliasID;
VTDWORD dwFlags;
VTWORD szwOriginal[ SCCVW_FONTNAMEMAX ];
VTWORD szwAlias[ SCCVW_FONTNAMEMAX * SCCVW_MAXALIASES ]
} SCCVWFONTALIAS, * PSCCVWFONTALIAS;

Parameters

- dwSize: Must be set by the developer to sizeof(SCCVWFONTALIAS).

- dwAliasID: ID of the aliasing in the current list of aliases. In Image Export, the default is that no alias is applied.

- dwFlags: The usage of these flags depends on whether this structure is being used with the DASetOption or DAGetOption message. It should be set to one of the following:

- SCCVW_FONTALIAS_COUNT (DAGetOption): dwAliasID will be filled with the count of current font aliases for that device.

- SCCVW_FONTALIAS_ALIASNAME (DASetOption): The alias of szwAlias for szwOriginal will be used when szwOriginal is not available on the device. When a font alias is added to the list, this can affect the alias count. If an alias already exists for szwOriginal, the new szwAlias will replace it.

- SCCVW_FONTALIAS_ALIASNAME (DAGetOption): szwAlias will be filled if there is an alias in the alias list for the font in szwOriginal on that device.

- SCCVW_FONTALIAS_GETALIASBYID (DAGetOption): szwAlias and szwOriginal will be filled by the technology for the alias in the numbered slot identified by the ID.

- SCCVW_FONTALIAS_GETALIASID (DAGetOption): dwAliasID will be set for the font in szwOriginal. If none exists, the dwAliasID will be 0xFFFFFFF.

- SCCVW_FONTALIAS_REMOVEALIASBYID (DASetOption): The alias in that slot will be removed if one exists. When a font alias is removed from the list, this can affect the other alias IDs.

- SCCVW_FONTALIAS_REMOVEALIASBYNAME (DASetOption): The alias for the font szwOriginal will be removed from the alias list if one exists. When a font alias is removed from the list, this can affect the other alias IDs.

- SCCVW_FONTALIAS_REMOVEALL (DASetOption): The alias list will be cleared out and the count will be zero.

- SCCVW_FONTALIAS_USEDEFAULTS (DASetOption): This clears the existing alias list and sets it to a list of default aliases that is variable by platform.

- szwOriginal: This represents the original name of a font that will be mapped when this font is not available. This name should be a Unicode string.

- szwAlias: This represents the new name of a font that will be used as a replacement for the unmapped font named in szwOriginal. This name should be a Unicode string.

Data

The technology assumes the following default mappings. The first value is the szwOriginal Value, the second is the szwAlias Value.

- Chicago = Arial

- Geneva = Arial

- New York = Times New Roman

- Helvetica = Arial

- Helv = Arial

10.1.8.3 SCCOPT_RENDER_EMBEDDED_FONTS

This option allows you to disable the use of embedded fonts in PDF input files.

10.1.8.4 SCCOPT_STROKE_TEXT

This option is used to stroke out (display as graphical primitives) text in an AutoCAD file. Setting this option to FALSE would improve performance, but the visual fidelity may be compromised.

- If the export for the conversion is text only, text is never stroked out.

- If the export is not text only, and the drawing is perspective, text will always be stroked out (regardless of this option). This is due to the fact that in non-text only situations visual fidelity is of importance, and handling of textual objects in perspective drawings is more accurate with stroked out text. If the conversion is non-text only and the drawing is not perspective, this option determines if text should be stroked.

Note that when this option is TRUE, some special characters appear as asterisks or question marks due to limited support of characters for stroking out text.

10.1.10 Callbacks

This section discusses callback options.

10.1.10.1 SCCOPT_EX_CALLBACKS

This is an advanced option that casual users of Image Export may ignore.

This option is used to disable callbacks being made from Image Export. Callbacks that are disabled will behave as if they were made and the developer had returned SCCERR_NOTHANDLED.

The option takes a VTDWORD field of flags. When the flag is set, the callback is enabled. By default, all callbacks are enabled. You can activate multiple callbacks by bitwise OR-ing them together. You can also disable multiple callbacks by bitwise &-ing the SCCEX_CALLBACKFLAG_ALLENABLED value with the one's complement of the corresponding callback flags. The following #defines are to be used for enabling the various callbacks:

Flag

Associated Callbacks

SCCEX_CALLBACKFLAG_CREATENEWFILE

EX_CALLBACK_ID_CREATENEWFILE

SCCEX_CALLBACKFLAG_NEWFILEINFO

EX_CALLBACK_ID_NEWFILEINFO

In addition, the following two special values are available:

- SCCEX_CALLBACKFLAG_ALLDISABLED: Disables the receipt of all callbacks. Additionally, bitwise OR-ing this value with one or more flags enables the corresponding callbacks. For example, SCCEX_CALLBACKFLAG_ALTLINK | SCCEX_CALLBACKFLAG_CREATENEWFILE enables the ALTLINK and CREATENEWFILE callbacks, but disables all others.

- SCCEX_CALLBACKFLAG_ALLENABLED: Enables the receipt of all callbacks. Additionally, bitwise &-ing this value with the one's complement of one or more flags disables the corresponding callbacks. For example, SCCEX_CALLBACKFLAG_ALLENABLED& (~SCCEX_CALLBACKALTLINK & ~SCCEX_CALLBACKFLAG_CREATENEWFILE) disables the ALTLINK and CREATENEWFILE callbacks, but enables all others.

10.1.10.2 SCCOPT_EX_UNICODECALLBACKSTR

This option determines the format of strings used in the callback functions. For those structures that contain a field of type BYTE or LPBYTE, a comparable structure has been added which has a similar field of type WORD or LPWORD. These structures will have the same name as the original structure, with the addition of a "W" at the end.

When this option is set to TRUE, any time a callback uses a structure with a string, it will use the new structure. Also, any strings that the callback function returns will be expected to follow the same guidelines. If the option is set to FALSE, all callbacks will use single-byte character strings.

For example, if this option is set to TRUE, and the EX_CALLBACK_ID_CREATENEWFILE callback is called, the pExportData parameter to the callback will point to an EXURLFILEIOCALLBACKDATAW structure. If the option is set to FALSE, the pCommandOrInfoData parameter will point to an EXURLFILEIOCALLBACKDATA structure.

This option should be set before EXOpenExport is called.

VTDWORD dwMMapBufferSize;    /* maximum size for the I/O
Memory Map buffer in KB */
VTDWORD dwTempBufferSize;    /* maximum size for the memory-
mapped temp files in KB */
VTDWORD dwFlags;             /* use flags */
} SCCBUFFEROPTIONS, *PSCCBUFFEROPTIONS;

Parameters

- dwReadBufferSize: Used to define the number of bytes that will read from disk into memory at any given time. Once the buffer has data, further file reads will proceed within the buffer until the end of the buffer is reached, at which point the buffer will again be filled from the disk. This can lead to performance improvements in many file formats, regardless of the size of the document.

- dwMMapBufferSize: Used to define a maximum size that a document can be and use a memory-mapped I/O model. In this situation, the entire file is read from disk into memory and all further I/O is performed on the data in memory. This can lead to significantly improved performance, but note that either the entire file can be read into memory, or it cannot. If both of these buffers are set, then if the file is smaller than the dwMMapBufferSize, the entire file will be read into memory; if not, it will be read in blocks defined by the dwReadBufferSize.

- dwTempBufferSize: The maximum size that a temporary file can occupy in memory before being written to disk as a physical file. Storing temporary files in memory can boost performance on archives, files that have embedded objects or attachments. If set to 0, all temporary files will be written to disk.

- dwFlags

- SCCBUFOPT_SET_READBUFSIZE 1

- SCCBUFOPT_SET_MMAPBUFSIZE 2

- SCCBUFOPT_SET_TEMPBUFSIZE 4

To set any of the three buffer sizes, set the corresponding flag while calling dwSetOption.

Default

The default settings for these options are:

- #define SCCBUFOPT_DEFAULT_READBUFSIZE 2: A 2KB read buffer.

- #define SCCBUFOPT_DEFAULT_MMAPBUFSIZE 8192: An 8MB memory-map size.

- #define SCCBUFOPT_DEFAULT_TEMPBUFSIZE 2048: A 2MB temp-file limit.

Minimum and maximum sizes for each are:

- SCCBUFOPT_MIN_READBUFSIZE 1: Read one Kbyte at a time.

- SCCBUFOPT_MIN_MMAPBUFSIZE 0: Don't use memory-mapped input.

- SCCBUFOPT_MIN_TEMPBUFSIZE 0: Don't use memory temp files

- SCCBUFOPT_MAX_READBUFSIZE 0x003fffff, SCCBUFOPT_MAX_MMAPBUFSIZE 0x003fffff, SCCBUFOPT_MAX_TEMPBUFSIZE 0x003fffff: These maximums correspond to the largest file size possible under the 4GB DWORD limit.

10.1.11.2 SCCOPT_TEMPDIR

From time to time, the technology needs to create one or more temporary files. This option sets the directory to be used for those files.

It is recommended that this option be set as part of a system to clean up temporary files left behind in the event of abnormal program termination. By using this option with code to delete files older than a predefined time limit, the OEM can help to ensure that the number of temporary files does not grow without limit.

SCCUTTEMPDIRSPEC structure

10.1.11.2.1 SCCUTTEMPDIRSPEC Structure

This structure is used in the SCCOPT_TEMPDIR option.

typedef struct SCCUTTEMPDIRSPEC
{
VTDWORD   dwSize;
VTDWORD   dwSpecType;
VTBYTE    szTempDirName[SCCUT_FILENAMEMAX];
} SCCUTTEMPDIRSPEC,  * LPSCCUTTEMPDIRSPEC;

There is currently a limitation. dwSpecType describes the contents of szTempDirName. Together, dwSpecType and szTempDirName describe the location of the source file. The only dwSpecType values supported at this time are:

- IOTYPE_ANSIPATH: Windows only. szTempDirName points to a NULL-terminated full path name using the ANSI character set and FAT 8.3 (Win16) or NTFS (Win32 and Win64) file name conventions.

- IOTYPE_UNICODEPATH: Windows only. szTempDirName points to a NULL-terminated full path name using the Unicode character set and NTFS file name conventions. Note that the length of the path name is limited to SCCUT_FILENAMEMAX bytes, or (SCCUT_FILENAMEMAX / 2) double-byte Unicode characters.

- IOTYPE_UNIXPATH: UNIX platforms only. szTempDirName points to a NULL-terminated full path name using the system default character set and UNIX path conventions. Unicode paths can be accessed on UNIX platforms by using a UTF-8 encoded path with IOTYPE_UNIXPATH.

Specifically not supported at this time is IOTYPE_REDIRECT.

Users should also note that temporary files created by the technology are not subject to callbacks (such as EX_CALLBACK_ID_CREATENEWFILE) normally made when files are created.

Parameters

- dwSize: Set to sizeof(SCCUTTEMPDIRSPEC).

- dwSpecType: IOTYPE_ANSIPATH, IOTYPE_UNICODEPATH, or IOTYPE_UNIXPATH

- szTempDirName: The path to the directory to use for the temporary files. Note that if all SCCUT_FILENAMEMAX bytes in the buffer are filled, there will not be space left for file names.

Default

The system default directory for temporary files. On UNIX systems, this is the value of environment variable $TMP. On Windows systems, it is the value of environment variable %TMP%.

10.1.11.3 SCCOPT_DOCUMENTMEMORYMODE

This option determines the maximum amount of memory that the chunker may use to store the document's data, from 4 MB to 1 GB. The more memory the chunker has available to it, the less often it needs to re-read data from the document.

Part III

Using the Java API

This section provides details about using the SDK with the Java API.

Part III contains the following chapters:

- Chapter 11, "Introduction to the Java API"

- Chapter 12, "Image Export Java Classes"

11 Introduction to the Java API

This chapter provides an introduction to the Java API.

The Java API is an add-on to the Outside In Export SDKs that enables developers to use Java to create applications using Outside In Technology.

11.1 Requirements

To use the API, the following set of modules and tools are required:

- Java JDK 6 or later

- The Outside In developer's redistributable modules for your product(s)

- The API libraries:

- oilink.jar - The Java library to access the Outside In technologies

- oilink (on Unix)/oilink.exe (on Windows) - The bridge modules between Java and the C-APIs.

All of the Outside In modules should be in the same directory as oilink.jar.

The SDK includes sample source code to demonstrate how such web applications may be written. These sample applications are written as simply and generically as possible, and will not fill all of the needs of your particular application. They are intended for instructional purposes only.

11.2 Getting Started

There are two steps in developing applications using the APIs. In the first step, you configure the environment to create your application (typical programming tasks not directly related to these APIs); and in the second step, you generate code to utilize the functionality of these libraries.

11.2.1 Configure the Environment

To set up the environment to create a Java application, you need to add the oilink.jar library to your project. (This can be done in Eclipse in the Project Properties dialog by selecting Java Build Path properties > Libraries tab > Add external JARs > browse to oilink.jar.)

11.2.2 Generate Code

Sample application code included with the SDK, OITSample, is a minimal demonstration of how to use this API.

All the functionality required to perform a conversion is provided in an Exporter object. The basic process of exporting a file involves the following tasks:

1. Create an Exporter object.

2. Configure the export.

3. Set the source and primary destination files.

4. Set the output type.

5. (Optional) Provide a callback handler.

6. Run the export.

Tasks 2 through 5 can be done in any order between the first and last task.

11.2.2.1 Create an Exporter Object

To obtain access to the Outside In functionality, you should call the utility function in the "OutsideIn" class. This will provide you an instance of an Exporter Object.

Exporter exporter = OutsideIn.newLocalExporter();

11.2.2.2 Configure the Output

The Outside In API is highly configurable, and presents numerous options to fine-tune the way a document is exported. Each option has a "set" and "get" method to set or retrieve the currently set value.

exporter.setPerformExtendedFI(true);
int timezoneOffset = exporter.getTimeZoneOffset();

11.2.2.3 Set the Source and Primary Destination Files

You are required to specify the source file and the destination file. This is done similarly to setting options using "set" methods.

exporter.setSourceFile(inputFile);
exporter.setDestinationFile(outputFile);

There are other options that can be set at this time to specify the way to handle the input file, such as providing a SourceFormat to provide a mechanism to handle the input file in a different format than that which it is identified as.

The API also supports opening certain types of embedded documents from within an input file. For example, a .zip file may contain a number of embedded documents; and an email message saved as a .msg file may contain attachments. The API provides the means of opening these types of embedded documents. This can be done by opening the parent document and then the embedded document can be opened through this exporter object.

// subdocId is the sequential number of the node in the archive file
Exporter exporterNode = exporter.newTreeNodeExporter(subdocId);

11.2.2.4 Set the Output Type

In this step, you specify the output format.

exporter.setDestinationFormat(FileFormat.FI_JPEG);

11.2.2.5 Provide a Callback Handler

Outside In Technology provides callbacks that allow the developer to intervene at critical points in the export process. To respond to these callbacks, you have to subscribe to any messages that you are interested in by overriding the message handlers from the Callback class. After creating an object of this class, set the callback option to this object and the messages will be passed to your object.

class CallbackHandler extends Callback
{
… // implementation of messages to handle - described in the API documentation
}
CallbackHandler callback = new CallbackHandler();
exporter.setCallbackHandler(callback);

11.2.2.6 Run the Export

After all the previous steps are completed, you can produce the desired output.

exporter.export();

12 Image Export Java Classes

This chapter describes the Image Export Java classes.

12.1 Annotation Class

Annotation is an abstract base class for the Annotation objects.

Accessors

- Height (long) Height of area in coordinates or rows

void setHeight(long)
long getHeight()

- Left (long) Leftmost coordinate or column

void setLeft(long)
long getLeft()

- Opacity (float) Opacity of the annotation. Range 0.0 - 1.0; setting opacity to 0 makes the annotation invisible

float getOpacity()

- SectionIndex (long) 0-based page/sheet/image/slide index

void setSectionIndex(long)
long getSectionIndex()

- Top (long) Top coordinate or row

Annotation.UnitTypeValue getUnits()

- UserId (long) User Data

void setUserId(long)
long getUserId()

- Width (long) Width of area in coordinates or columns

long getWidth()

Annotation.UnitTypeValue Enumeration

The UnitTypeValue is an enumeration of the various unit types that annotation positions can be described in.

- Pixels: Units specified in Pixels

- Twips: Units specified in Twips (1/1440th of an inch)

- Cells: Units specified in cell positions

12.2 Callback Class

Callback messages are notifications that come from Outside In during the export process, providing information and sometimes the opportunity to customize the generated output. To access callback messages, your code must create an object that inherits from Callback and pass it through the API's SetCallbackHandler method. Your object can implement methods that override the default behavior for whichever methods your application is interested in.

Callback has two methods that you can override: createNewFile and newFileInfo.

12.2.1 createNewFile

CreateNewFileResponse createNewFile( FileFormat parentOutputId,  FileFormat outputId,
AssociationValue association, String path)  throws IOException

This callback is made any time a new output file needs to be generated. This gives the developer the chance to affect where the new output file is created, how it is named, and the URL (if any) used to reference the file.

Parameters

- parentOutputId: File format identifier of the parent file

- outputId: File format identifier of the file created

- association: An AssociationValue that describes relationship between the primary output file and the new file.

- path: Full path of the file to be created

Return Value

To take action in response to this notification, return a CreateNewFileResponse object with the new file information. If you wish to accept the defaults for the path and URL, you may return null.

12.2.1.1 CreateNewFileResponse Class

This is a class to define a new output file location in response to a CreateNewFile callback. If you do not wish to change the path to the new output file, you may use the path as received. If you do not wish to specify the URL for the new file, you many specify it as null.

Constructor

CreateNewFileResponse(File file, String url) throws IOException

- file: File object containing the full path to the new file

- url: A new URL that references the newly created file. This parameter can be null.

AssociationValue Enumeration

This enumeration defines, for a new file created by an export process, the different possible associations between the new file and the primary output file. Its value may be one of the following:

- ROOT - indicates the primary output file

- CHILD - a new file linked (directly or indirectly) from the primary output file

- SIBLING - indicates new files not linked from the primary output file

- COPY - the file was copied as a part of a template macro operation.

- REQUIREDNAME - not used

Note that some of these relationships will not be possible in all Outside In Export SDKs.

12.2.2 newFileInfo

void newFileInfo( FileFormat parentOutputId, FileFormat outputId,
AssociationValue association, String path, String url) throws IOException

This informational callback is made just after each new file has been created.

Parameters

- parentOutputId: File format identifier of the parent file

- outputId: File format identifier of the file created

- association: An AssociationValue that describes relationship between the primary output file and the new file.

- path: Full path of the file created

- url: URL that references the newly created file

Example

Here is a basic callback handler that notifies an application that it has received newFileInfo notifications.

public static class CallbackHandler extends Callback
{
myApplication m_theApp;

public CallbackHandler( myApplication app )
{
m_theApp = app;
}

public void newFileInfo(FileFormat parentOutputId,
FileFormat outputId, AssociationValue association,
String path, String url) throws IOException
{
if( association == AssociationValue.ROOT )
m_theApp.primaryOutputIsReady(true);

m_theApp.newOutputFile(path);
}
}

12.3 ColorInfo Class

ColorInfo is a class to define a color or to use a default color in appropriate cases.

Constructors

ColorInfo()

Initializes an ColorInfo object to use the default color.

public ColorInfo(byte red,
byte green,
byte blue)

Initializes a ColorInfo object with the specified RGB values.

Accessors

- byte getBlue() - Blue component of the color

- byte getGreen() - Green component of the color

- byte getRed() - Red component of the color

- boolean isDefaultColor() - Returns true if the default color is used

12.4 Exporter Interface

This section describes the properties and methods of Exporter.

bOpenForNonSequentialAccess : If set to true would open the archive file in the special access mode. Note that turning this flag on a non-archive file will throw an exception at RunExport time.

12.4.2.1 BiDiReorderMethod

OIT Option ID: SCCOPT_REORDERMETHOD

This option controls how the technology reorders bidirectional text.

Data Type

- BiDiReorderMethodValue

BiDiReorderMethodValue Enumeration

One of the following values:

- UNICODEOFF: This disables any processing for bidirectional characters. This option is the default.

- UNICODELTOR: Characters displayed using the Unicode bidirectional algorithm assuming a base left-to-right order. Use this option to enable bidirectional rendering.

- UNICODERTOL: Characters displayed using the Unicode bidirectional algorithm assuming a base right-to-left order. Use this option to force starting bidirectional rendering in the right-to-left.

Default

UNICODEOFF

12.4.2.2 CropToContent

OIT Option ID: SCCOPT_GRAPHIC_CROPPING

When set to True, this option forces Image Export to crop whitespace from the edge of each output image. This includes margins and any unused space at the end of a page. This results in smaller output files without any loss of original input document content.

If there is no content, then no cropping is performed.

Data Type

boolean

12.4.2.3 DefaultInputCharacterSet

OIT Option ID: SCCOPT_DEFAULTINPUTCHARSET

This option is used in cases where Outside In cannot determine the character set used to encode the text of an input file. When all other means of determining the file's character set are exhausted, Outside In will assume that an input document is encoded in the character set specified by this option. This is most often used when reading plain-text files, but may also be used when reading HTML or PDF files.

12.4.2.4 DefaultRenderFont

OIT Option ID: SCCOPT_DEFAULTPRINTFONT

This option sets the font to use when the chunker-specified font is not available on the system. It is also the font used when the font in source file is not available on the system performing the conversion.

Class members:

string strFaceName

UInt16 FontHeight

12.4.2.5 DefaultPageMargins

This option specifies the top, left, bottom and right margins in twips from the edges of the page. For instance, setting all the values to 1440 creates a 1-inch margin on all sides. Page margins will only be applied when formatting word processing, database and spreadsheet files.

Please note all margins are applied before scaling with the PageFitMode option. This option is overridden when the UseDocumentPageSettings option is set to true and print margins are specified in the input document. This option does not affect the output of bitmap, presentation, vector or archive files.

Data Type

Margins

Data

A Margins object with the margins on the 4 sides defined.

Default

1 inch for all margins (1440, 1440, 1440, 1440)

12.4.2.6 DocumentMemoryMode

OIT Option ID: SCCOPT_DOCUMENTMEMORYMODE

This option determines the maximum amount of memory that the chunker may use to store the document's data, from 4 MB to 1 GB. The more memory the chunker has available to it, the less often it needs to re-read data from the document.

Data

- SMALLEST: 1 - 4MB

- SMALL: 2 - 16MB

- MEDIUM: 3 - 64MB

- LARGE: 4 - 256MB

- LARGEST: 5 - 1 GB

Default

SMALL: 2 - 16MB

12.4.2.7 EmailHeaders

OIT Option ID: SCCOPT_WPEMAILHEADEROUTPUT

This option controls rendering of email headers.

Data

- ALL: Displays all available email headers.

- STANDARD: Displays "To," "From," "Subject," "CC," "BCC," "Date Sent," and "Attachments" header fields only. The filter outputs any fields not listed above as hidden fields, so they will not display.

- NONE: Displays no email header fields.

- CUSTOM

Default

STANDARD

12.4.2.8 FallbackFormat

This option controls how files are handled when their specific application type cannot be determined. This normally affects all plain-text files, because plain-text files are generally identified by process of elimination, for example, when a file isn't identified as having been created by a known application, it is treated as a plain-text file. It is recommended that None be set to prevent the conversion from exporting unidentified binary files as though they were text, which could generate many pages of "garbage" output.

Data Type

FallbackFormatValue

FallbackFormatValue Enumeration

- TEXT: Unidentified file types will be treated as text files.

- NONE: Outside In will not attempt to process files whose type cannot be identified

Default

TEXT

12.4.2.9 FitHeightToPages

OIT Option ID: SCCOPT_SSPRINTSCALEXHIGH

This option will fit the spreadsheet image to the number of vertical pages specified. The setting for this option will have no effect unless the SSPrintFitToPage option is set to FitToPages.

Data Type

long

Default

1

12.4.2.10 FitWidthToPages

OIT Option ID: SCCOPT_SSPRINTSCALEXWIDE

This option will fit the spreadsheet image to the number of horizontal pages specified. The setting for this option will have no effect unless the SSPrintFitToPage option is set to FitToPages.

Data Type

long

Default

1

12.4.2.11 FontAliasList

This option enables the capability to specify which font on the system should be used when a specific font referenced in the original file is not available. A different alias can be set for each font desired to be mapped.

Data Type

FontAliases

Data

A FontAliases object with a list of font matchings.

Default

Windows and Unix PrintAlias defaults

12.4.2.12 GraphicHeight

OIT Option ID: SCCOPT_GRAPHIC_HEIGHT

This option defines the absolute height in pixels to which exported graphics will be resized. If this option is set and the GraphicWidth option is not, the width of the image will be calculated based on the aspect ratio of the source image. The developer should be aware that very large values for this option or GraphicWidth could produce images whose size exceeds available system memory, resulting in conversion failure.

If you are exporting a non-graphic file (word processing, spreadsheet or archive) and the settings for GraphicHeight and GraphicWidth do not match the aspect ratio of the original document, the exported image will have whitespace added so that the original file's aspect ratio is maintained.

The settings for the GraphicHeightLimit and GraphicWidth options can override the setting for GraphicHeight.

Data Type

long

12.4.2.13 GraphicHeightLimit

OIT Option ID: SCCOPT_GRAPHIC_HEIGHTLIMIT

Note that this option differs from the behavior of setting the height of graphics in that it sets an upper limit on the image height. Images larger than this limit will be reduced to the limit value. However, images smaller than this height will not be enlarged when using this option. Setting the height using GraphicHeight causes all output images to be reduced or enlarged to be of the specified height.

Data Type

long

12.4.2.14 GraphicOutputDPI

OIT Option ID: SCCOPT_GRAPHIC_OUTPUTDPI

This option allows the user to specify the output graphics device's resolution in DPI and only applies to images whose size is specified in physical units (in/cm). For example, consider a 1" square, 100 DPI graphic that is to be rendered on a 50 DPI device (GraphicOutputDPI is set to 50). In this case, the size of the resulting TIFF, BMP, JPEG, GIF, or PNG will be 50 x 50 pixels.

In addition, the special #define of SCCGRAPHIC_MAINTAIN_IMAGE_DPI, which is defined as 0, can be used to suppress any dimensional changes to an image. In other words, a 1" square, 100 DPI graphic will be converted to an image that is 100 x 100 pixels in size. This value indicates that the DPI of the output device is not important. It extracts the maximum resolution from the input image with the smallest exported image size.

Setting this option to SCCGRAPHIC_MAINTAIN_IMAGE_DPI may result in the creation of extremely large images. Be aware that there may be limitations in the system running this technology that could result in undesirably large bandwidth consumption or an error message. Additionally, an out of memory error message will be generated if system memory is insufficient to handle a particularly large image.

Also note that the SCCGRAPHIC_MAINTAIN_IMAGE_DPI setting will force the technology to use the DPI settings already present in raster images, but will use the current screen resolution as the DPI setting for any other type of input file.

For some output graphic types, there may be a discrepancy between the value set by this option and the DPI value reported by some graphics applications. The discrepancy occurs when the output format uses metric units (DPM, or dots per meter) instead of English units (DPI, or dots per inch). Depending on how the graphics application performs rounding on meters to inches conversions, the DPI value reported may be 1 unit more than expected. An example of a format which may exhibit this problem is PNG.

The maximum value that can be set is 2400 DPI; the default is 96 DPI.

Data Type

long

12.4.2.15 GraphicRenderAsPage

OIT Option ID: SCCOPT_GRAPHIC_RENDERASPAGE

GraphicRenderAsPage affects the way raster (bitmapped) images such as TIFF, JPG, and PNG are handled. The default behavior for Image Export is to export such images as copies of the input document, scaled according to the width and height options set by the caller. If GraphicRenderAsPage is enabled, the output produced by Image Export will look like a printed page, with the image placed on a white rectangle representing a virtual page. As usual, the dimensions of the entire image, including the virtual page, will be controlled by the normal Image Export output width and height settings. The margins into which the image will be placed will be controlled by existing Outside In print margin options. The image itself will be attempted to be scaled to its true (physical) size, or scaled down to fit within the margins if necessary.

Data Type

boolean

Data

- true: Raster file images are fit to page.

- false: Raster file images are not fit to page.

Default

false

12.4.2.16 GraphicSizeLimit

OIT Option ID: SCCOPT_GRAPHIC_SIZELIMIT

This option is used to set the maximum size of the exported graphic in pixels. It may be used to prevent inordinately large graphics from being converted to equally cumbersome output files, thus preventing bandwidth waste.

This setting takes precedence over all other options and settings that affect the size of a converted graphic.

When creating a multi-page TIFF file, this limit is applied on a per page basis. It is not a pixel limit on the entire output file.

Data Type

long

12.4.2.17 GraphicSizeMethod

OIT Option ID: SCCOPT_GRAPHIC_SIZEMETHOD

This option determines the method used to size graphics. The developer can choose among three methods, each of which involves some degree of trade off between the quality of the resulting image and speed of conversion.

Using the quick sizing option results in the fastest conversion of color graphics, though the quality of the converted graphic will be somewhat degraded. The smooth sizing option results in a more accurate representation of the original graphic, as it uses anti-aliasing. Antialiased images may appear smoother and can be easier to read, but rendering when this option is set will require additional processing time. The grayscale only option also uses antialiasing, but only for grayscale graphics, and the quick sizing option for any color graphics.

The smooth sizing option does not work on images which have a width or height of more than 4096 pixels.

Data

- QUICKSIZING

- SMOOTHSIZING

- SMOOTHGRAYSCALESIZING

12.4.2.18 GraphicWidth

OIT Option ID: SCCOPT_GRAPHIC_WIDTH

This option defines the absolute width in pixels to which exported graphics will be resized. If this option is set and the GraphicHeight option is not, the height of the image will be calculated based on the aspect ratio of the source image. The developer should be aware that very large values for this option or GraphicHeight could produce images whose size exceeds available system memory, resulting in conversion failure.

If you are exporting a non-graphic file (word processing, spreadsheet or archive) and the settings for GraphicHeight and GraphicWidth do not match the aspect ratio of the original document, the exported image will have whitespace added so that the original file's aspect ratio is maintained.

The settings for the GraphicHeightLimit and GraphicWidthLimit options can override the setting for GraphicWidth.

Data Type

long

12.4.2.19 GraphicWidthLimit

OIT Option ID: SCCOPT_GRAPHIC_WIDTHLIMIT

This option allows a hard limit to be set for how wide in pixels an exported graphic may be. Any images wider than this limit will be resized to match the limit. It should be noted that regardless whether the GraphicHeightLimit option is set or not, any resized images will preserve their original aspect ratio.

Note that this option differs from the behavior of setting the width of graphics by using GraphicWidth in that it sets an upper limit on the image width. Images larger than this limit will be reduced to the limit value. However, images smaller than this width will not be enlarged when using this option. Setting the width using GraphicWidth causes all output images to be reduced or enlarged to be of the specified width.

Data Type

long

12.4.2.20 GridMaxPageHeight

OIT Option ID: SCCOPT_MAXSSDBPAGEHEIGHT

Normally, the size of images generated from spreadsheet worksheets and database tables is limited to the size of the page defined by the input document's page size information and how the UseDocumentPageSettings, GraphicWidth and GraphicHeight options are set. If, after scaling is factored in, the resulting image is too large to fit on a single page, it is split up into multiple pages.

The GridMaxPageWidth and GridMaxPageHeight options are used to change the size of a page to match the scaled size of the page being rendered - within limits. The key reason for those limits is that rendering very large pages can easily overwhelm the memory available on the system. When using this feature, a calculation should be made to be sure that the values passed in work within said memory limits. The values for these two options will override the current page dimensions if necessary.

Data Type

long

Data

The maximum page height (including margins) specified in twips (1440 twips are in 1 inch). If the value specified is smaller than the page height, then an error will be returned.

12.4.2.21 GridMaxPageWidth

OIT Option ID: SCCOPT_MAXSSDBPAGEWIDTH

See the documentation for GridMaxPageHeight for a full discussion of how this option works and interacts with other options affecting the page size of images generated from spreadsheet and database pages.

Data Type

long

Data

The maximum page width (including margins) specified in twips (1440 twips are in 1 inch). If the value specified is smaller than the page width, then Image Export will return an error.

12.4.2.22 IECondCommentMode

OIT Option ID: SCCOPT_HTML_COND_COMMENT_MODE

Some HTML input files may include "conditional comments", which are HTML comments that mark areas of HTML to be interpreted in specific versions of Internet Explorer, while being ignored by other browsers. This option allows you to control how the content contained within conditional comments will be interpreted by Outside In's HTML parsing code.

Data

- NONE: Don't output any conditional comment

- IE5: Include the IE5 comments

- IE6: Include the IE6 comments

- IE7: Include the IE7 comments

- IE8: Include the IE8 comments

- IE9: Include the IE9 comments

- ALL: Include all conditional comments

12.4.2.23 IgnorePassword

OIT Option ID: SCCOPT_IGNORE_PASSWORD

This option can disable the password verification of files where the contents can be processed without validation of the password. If this option is not set, the filter should prompt for a password if it handles password-protected files.

Data Type

boolean

12.4.2.24 InternalRendering

OIT Option ID: SCCOPT_RENDERING_PREFER_OIT

This option is valid on 32- and 64-bit Linux, 32-bit SunOS SPARC, 32-bit HP-UX RISC, and 32-bit AIX PPC.

When this option is set to TRUE, the technology will attempt to use its internal graphics code to render fonts and graphics. When set to FALSE, the technology will render images using the operating system's native graphics subsystem (X11 on UNIX/Linux platforms). This requires that there be an X11 display and a valid DISPLAY variable, regardless of the type of input document.

It is important for the system to be able to locate usable fonts when this option is set to TRUE. Only TrueType fonts (*.ttf or *.ttc files) are currently supported. To ensure that the system can find them, make sure that the environment variable GDFONTPATH includes one or more paths to these files. If the variable GDFONTPATH can't be found, the current directory is used. If fonts are called for and cannot be found, Image Export will exit with an error. Oracle does not provide fonts with any Outside In product.

Note:

Note that the maximum total path size for paths included in GDFONTPATH is 256 characters - paths longer than this will be truncated and will result in fonts not being discovered.

Data Type

boolean

12.4.2.25 ISODateTimes

OIT Option ID: SCCOPT_FORMATFLAGS

When this flag is set, all Date and Time values are converted to the ISO 8601 standard. This conversion can only be performed using dates that are stored as numeric data within the original file.

Data Type

boolean

Default

false

12.4.2.26 JPEGQuality

OIT Option ID: SCCOPT_JPEG_QUALITY

This option allows the developer to specify the lossyness of JPEG compression. The option is only valid if the dwOutputID parameter of the EXOpenExport function is set to FI_JPEGFIF, FI_PDF, FI_PDFA, or FI_PDFA_2.

Data Type

long

Data

A value from 1 to 100, with 100 being the highest quality but the least compression, and 1 being the lowest quality but the most compression.

Default

100

12.4.2.27 LotusNotesDirectory

OIT Option ID: SCCOPT_LOTUSNOTUSDIRECTORY

This option allows the developer to specify the location of a Lotus Notes or Domino installation for use by the NSF filter. A valid Lotus installation directory must contain the file nnotes.dll.

Type (Common): String

Data

A path to the Lotus Notes directory.

Default

If this option isn't set, then OIT will first attempt to load the Lotus library according to the operating system's PATH environment variable, and then attempt to find and load the Lotus library as indicated in HKEY_CLASSES_ROOT\Notes.Link.

12.4.2.28 PageDirection

OIT Option ID: SCCOPT_SSPRINTDIRECTION

This option controls the pattern in which the pages are rendered, either across first and then down, or down first and then across.

This option is overridden when the UseDocumentPageSettings option is set to TRUE and print direction is specified in the input document.

Data

- PageDirectionValue.ACROSS: Specifies that pages are printed across first and then down.

- PageDirectionValue.DOWN: Specifies that pages are printed down first and then across.

Default

PageDirectionValue.DOWN

12.4.2.29 PageFitMode

OIT Option ID: SCCOPT_DBPRINTFITTOPAGE

OIT Option ID: SCCOPT_SSPRINTFITTOPAGE

This option scales a spreadsheet file or database image to a certain percent or to a page width or height. However, in an effort to preserve readability after scaling, Image Export will not shrink a database document to under approximately one-third of its original size.

It should be noted that when this option is set to NOMAP, the pages of the database file are printed down first and then across.

Please note that any margins applied as a result of settings for the DefaultPageMargins option will be included in any scaling that is applied to the output image as a result of settings for this option.

This option is overridden when the UseDocumentPageSettings option is set to TRUE and fitting the page to the printer's image limits is specified in the input document.

Data

- NOMAP: No scaling is performed on the spreadsheet or database image. It will render in its original size onto as many pages as are required to fit the data.

- FITTOWIDTH: Scale the spreadsheet or database image in the rendered image so it is no larger than one page wide.

- FITTOHEIGHT: Scale the spreadsheet or database image in the rendered image so it is no larger than one page high.

- SCALE: Scale the spreadsheet or the database image in the rendered image using the scale value stored in the PageScalePercent option.

- FITTOPAGES: Scale the spreadsheet or the database image in the rendered image to fit to the number of pages specified in the FitHeightToPages and FitWidthToPages options. Since aspect ratio is maintained, the lesser of the two dimensions (width or height) will determine the scale factor. Note that if either FitHeightToPages or FitWidthToPages is set to 0, the value in the other option will be nullified.

Default

- SCALE: Scales the rendered image of the spreadsheet or database image using the scale value stored in the PageScalePercent option (which is 100 by default).

12.4.2.30 PageRange

OIT Option ID: SCCOPT_WHATTOPRINT

OIT Option ID: SCCOPT_PRINTSTARTPAGE

This option must take a value between 1 and 100. If any value outside of this range is used, the option will be ignored.

Data Type

long

Default

100

12.4.2.32 PDFReorderBiDi

OIT Option ID: SCCOPT_PDF_FILTER_REORDER_BIDI

This option controls whether or not the PDF filter will attempt to reorder bidirectional text runs so that the output is in standard logical order as used by the Unicode 2.0 and later specification. This additional processing will result in slower filter performance according to the amount of bidirectional data in the file.

PDFReorderBiDiValue Enumeration

This enumeration defines the type of Bidirection text reordering the PDF filter should perform.

- STANDARDBIDI: Do not attempt to reorder bidirectional text runs.

- REORDEREDBIDI: Attempt to reorder bidirectional text runs.

12.4.2.33 PerformExtendedFI

OIT Option ID: SCCOPT_FIFLAGS

This option affects how an input file's internal format (application type) is identified when the file is first opened by the Outside In technology. When the extended test flag is in effect, and an input file is identified as being either 7-bit ASCII, EBCDIC, or Unicode, the file's contents will be interpreted as such by the export process.

The extended test is optional because it requires extra processing and cannot guarantee complete accuracy (which would require the inspection of every single byte in a file to eliminate false positives.)

Data Type

boolean

Data

One of the following values:

- false: When this is set, standard file identification behavior occurs.

- true: If set, the File Identification code will run an extended test on all files that are not identified.

Default

- true

12.4.2.34 QuickThumbnail

OIT Option ID: SCCOPT_QUICKTHUMBNAIL

When this option is set to true the technology will render scaled images with a focus on speed and reduced overall memory usage. This focus on speed and memory usage, in some cases, will cause the resulting images to be less readable than when this option is set to false.

Data Type

boolean

Data

- true: Render scaled images as quick thumbnails.

- false: Render scaled images completely.

Default

true

12.4.2.35 RenderGridlines

It is used to expand the widths of cells that are hidden by virtue of having their row height or column width reduced to 0. This is a Boolean option that will leave the data hidden when it is FALSE, and show all hidden rows and columns when it is TRUE, displayed using the default row width or default column height.

Data Type

boolean

Default

false

12.4.2.39 ShowHiddenSpreadSheetData

The setting for this option determines whether or not hidden data (hidden columns, rows or sheets) in a spreadsheet will be included in the output. When set to false (the default), the hidden elements are not written. When set to true, they are placed in the output in the same manner as regular spreadsheet data.

Data Type

boolean

Default

false

12.4.2.40 StrictFile

When an embedded file or URL can't be opened with the full path, OutsideIn will sometimes try and open the referenced file from other locations, including the current directory. When this option is set, it will prevent OutsideIn from trying to open the file from any location other than the fully qualified path or URL.

Data Type

boolean

Default

false

12.4.2.41 TIFFByteOrder

Data Type

long

Data

Integer parameter from -96 to 96, representing 15-minute offsets from GMT. To query the operating system for the time zone set on the machine, specify SCC_TIMEZONE_USENATIVE.

Default

- 0: GMT time

12.4.2.47 TransparencyColor

OIT Option ID: SCCOPT_GRAPHIC_TRANSPARENCYCOLOR

This option allows the user to set the color used as the "transparency color" in the output graphic file. Naturally, this option is only used when the selected output graphic file format supports transparency (GIF and PNG only). If the option is not set, the default behavior is to use the same color value that the input file used as the transparency color.

Use the (r, g, b) macro to create the color value to pass to this option. The red, green and blue values are percentages of the color from 0-255 (with 255 being 100%). Note that this macro should be used to set a variable and that variable should then be passed to the set option routine (instead of trying to use the macro as part of the set option call directly).

Since there is no way to "unset" an option once it has been set, the developer may set the option to DefaultTransparencyColor if they wish to revert to the default behavior.

Class members:

byte Red

byte Green

byte Blue

Data

ColorInfo

Default

- new ColorInfo(): Use the same tranparency color as the source document.

Default

- 0x002a = "*"

12.4.2.49 UseDocumentPageSettings

OIT Option ID: SCCOPT_USEDOCPAGESETTINGS

This option is used to select the document's page layout information when rendering.

If true, the document's native (or author selected) page margins, paper size, page scaling and page orientation are used when available from the filter.

The values of the DefaultPageMargins, RenderGridlines, RenderHeadings, PageDirection, and PageFitMode options are overridden if this option is set to TRUE and the properties associated with those options are specified in the input document. Additionally, print area and page breaks in spreadsheet documents are ignored unless this option is set to true.

If false, the page margins, size, orientation and scaling are set to specific values rather than those in the native document. The page size is forced to 8 1/2" x 11" in portrait orientation, but this may be changed by setting the GraphicHeight and/or GraphicWidth options. The margins are forced 1" all around, but may be changed by setting the defaultMargins option. The scaling for the document will be set to 100%, although this may be changed by setting any of the various scaling options.

It should be noted that this option also affects page orientation for both input spreadsheets and word processing documents.

Data Type

Part IV

Using the .NET API

This section provides details about using the SDK with the .NET API.

Part IV contains the following chapters:

- Chapter 13, "Introduction to the .NET API"

- Chapter 14, "Image Export .NET Classes"

13 Introduction to the .NET API

This chapter is an introduction to the .NET API.

Outside In .NET is a set of class libraries and Windows DLLs that provides developers an easy interface to create .NET applications using Outside In Technology.

13.1 Requirements

To develop applications using the .NET APIs, the following set of modules and tools are required:

- The Outside In Technology (OIT) developer's redistributable modules for your product

- Visual Studio 2010 or later

- NET Framework 4.0 or later

- The API libraries:
outsidein.dll - The .NET libraries to access the Outside In technologies

oilink.dll and oilink.exe- The bridge modules between .NET and the C-APIs.

Google.ProtocolBuffers.dll - The cross language binary serialization provider.

13.2 Getting Started

There are two steps in developing applications using the APIs. In the first step, you would need to configure the environment to create your application (typical programming tasks not directly related to these APIs) and in the second step you would generate code to utilize the functionality of these libraries.

13.2.1 Configuring your Environment

To setup the environment to create a .NET application, you would need to add references to all the libraries. In order to use the Outside In components in your application, the following component should be referenced: outsidein.dll. (This can be done by using the Add Reference dialog box in Visual Studio.)

13.2.2 Generate Code

The sample application included with the SDK, OITsample, is a minimal demonstration of how to use this API.

All the functionality required to perform a conversion is provided in an Exporter object. The basic process of exporting a file involves the following tasks:

1. Create an Exporter object. To obtain access to the Outside In functionality, you should call the utility function in the "OutsideIn" class. This will provide you an instance of an Exporter Object.

2. Configure the export. The Outside In API is highly configurable, and presents numerous options to fine-tune the way a document is exported. Each option has a "set" and "get" method to set or retrieve the currently set value.

3. Set the source and primary destination files. You are required to specify the source file and the destination file. This is done similar to setting options using "set" methods.

4. Set the output type. In this step, you specify the output format.

5. (Optional) Provide a callback handler. The Outside In Technology provides callbacks that allow the developer to intervene at critical points in the export process. To respond to these callbacks, you would have to subscribe to any messages that you are interested in by overriding the message handlers from the "Callback" class. After creating an object of this class, set the callback option to this object and the messages will be passed to your object.

6. Run the export. After all the previous steps are completed, you can produce the desired output.

13.2.2.1 Create an Exporter Object

To obtain access to the Outside In functionality, you should call the utility function in the "OutsideIn" class. This will provide you an instance of an Exporter Object.

Exporter exporter = OutsideIn.OutsideIn.NewLocalExporter();

13.2.2.2 Configure the Output

The Outside In API is highly configurable, and presents numerous options to fine-tune the way a document is exported. Each option has a "set" and "get" method to set or retrieve the currently set value.

exporter.SetPerformExtendedFI(true);
int timezoneOffset = exporter.GetTimeZoneOffset();

13.2.2.3 Set the Source and Primary Destination Files

You are required to specify the source file and the destination file. This is done similarly to setting options using "set" methods.

exporter.SetSourceFile(inputFilename);

exporter.SetDestinationFile(outputFilename);

There are other options that can be set at this time to specify the way to handle the input file, such as providing a SourceFormat to provide a mechanism to handle the input file in a different format than that which it is identified as.

The API also supports opening certain types of embedded documents from within an input file. For example, a .zip file may contain a number of embedded documents; and an email message saved as a .msg file may contain attachments. The API provides the means of opening these types of embedded documents. This can be done by opening the parent document and then the embedded document can be opened through this exporter object.

// subdocId is the sequential number of the node in the archive file

Exporter exporterNode = exporter.NewTreeNodeExporter(subdocId);

13.2.2.4 Set the Output Type

In this step, you specify the output format.

exporter.SetDestinationFormat(FileFormat.FI_JPEG);

13.2.2.5 Provide a Callback Handler

Outside In Technology provides callbacks that allow the developer to intervene at critical points in the export process. To respond to these callbacks, you have to subscribe to any messages that you are interested in by overriding the message handlers from the Callback class. After creating an object of this class, set the callback option to this object and the messages will be passed to your object.

14 Image Export .NET Classes

This chapter describes the Image Export .NET classes.

14.1 Annotation Class

Annotation is an abstract base class for the Annotation objects.

Properties

- Height (Int64) Height of area in coordinates or rows

- Left (Int64) Leftmost coordinate or column

- Opacity (Single) Opacity of the annotation. Range 0.0 - 1.0; setting opacity to 0 makes the annotation invisible

- SectionIndex (Int64) 0-based page/sheet/image/slide index

- Top (Int64) Top coordinate or row

- Units (Annotation.UnitTypeValue) Type of units in which Height, Width, Left and Top are described

- UserId (Int64) User Data

- Width (Int64) Width of area in coordinates or columns

Annotation.UnitTypeValue Enumeration

The UnitTypeValue is an enumeration of the various unit types that annotation positions can be described in.

- Pixels: Units specified in Pixels

- Twips: Units specified in Twips (1/1440th of an inch)

- Cells: Units specified in cell positions

14.2 Callback Class

Callback messages are notifications that come from Outside In during the export process, providing information and sometimes the opportunity to customize the generated output. To access callback messages, your code must create an object that inherits from Callback and pass it through the API's SetCallbackHandler method. Your object can implement methods that override the default behavior for whichever methods your application is interested in.

Callback has two methods that you can override: CreateNewFile and NewFileInfo.

14.2.1 CreateNewFile

CreateNewFileResponse CreateNewFile( FileFormat ParentOutputId,  FileFormat OutputId,
Association Association, string Path)

This callback is made any time a new output file needs to be generated. This gives the developer the chance to affect where the new output file is created, how it is named, and the URL (if any) used to reference the file.

Parameters

- ParentOutputId: File format identifier of the parent file.

- OutputId: File format identifier of the file created.

- Association: An Association that describes relationship between the primary output file and the new file.

- Path: Full path of the file to be created.

Return Value

To take action in response to this notification, return a CreateNewFileResponse object with the new file information. If you wish to accept the defaults for the path and URL, you may return null.

14.2.1.1 CreateNewFileResponse Class

This is a class to define a new output file location in response to a CreateNewFile callback. If you do not wish to change the path to the new output file, you may use the path as received. If you do not wish to specify the URL for the new file, you many specify it as null.

Constructor

CreateNewFileResponse(FileInfo File, string URL)

- File: File object with full path to new file.

- URL: A new URL that references the newly created file. This parameter can be null.

Association Enumeration

This enumeration defines, for a new file created by an export process, the different possible associations between the new file and the primary output file. Its value may be one of the following:

- Root - indicates the primary output file

- Child - a new file linked (directly or indirectly) from the primary output file

- Sibling - indicates new files not linked from the primary output file

- Copy - the file was copied as a part of a template macro operation.

- RequiredName - not used

Note that some of these relationships will not be possible in all Outside In Export SDKs.

14.2.2 NewFileInfo

void NewFileInfo( FileFormat ParentOutputId, FileFormat OutputId,
Association Association, string Path, string URL)

This informational callback is made just after each new file has been created.

Parameters

- ParentOutputId: File format identifier of the parent file

- OutputId: File format identifier of the file created

- Association: An Association that describes relationship between the primary output file and the new file.

- Path: Full path of the file created

- URL: URL that references the newly created file

14.3 ColorInfo Class

ColorInfo is a class to define a color or to use a default color in appropriate cases.

Constructors

ColorInfo()

Initializes an ColorInfo object to use the default color.

public ColorInfo(Byte red,
Byte green,
Byte blue)

Initializes a ColorInfo object with the specified RGB values.

Properties

- Blue (Byte) - Blue component of the color

- Green (Byte) - Green component of the color

- Red (Byte) - Red component of the color

- UseDefault (Byte) - Set to true if the default color is used

14.4 Exporter Interface

This section describes the properties and methods of Exporter.

14.4.2.1 BiDiReorderMethod

OIT Option ID: SCCOPT_REORDERMETHOD

This option controls how the technology reorders bidirectional text.

Data Type

- BiDiReorderMethodValue

BiDiReorderMethodValue Enumeration

One of the following values:

- UnicodeOff: This disables any processing for bidirectional characters. This option is the default.

- UnicodeLToR: Characters displayed using the Unicode bidirectional algorithm assuming a base left-to-right order. Use this option to enable bidirectional rendering.

- UnicodeRToL: Characters displayed using the Unicode bidirectional algorithm assuming a base right-to-left order. Use this option to force starting bidirectional rendering in the right-to-left.

Default

UnicodeOff

14.4.2.2 CropToContent

OIT Option ID: SCCOPT_GRAPHIC_CROPPING

When set to True, this option forces Image Export to crop whitespace from the edge of each output image. This includes margins and any unused space at the end of a page. This results in smaller output files without any loss of original input document content.

If there is no content, then no cropping is performed.

Data Type

bool

14.4.2.3 DefaultInputCharacterSet

OIT Option ID: SCCOPT_DEFAULTINPUTCHARSET

This option is used in cases where Outside In cannot determine the character set used to encode the text of an input file. When all other means of determining the file's character set are exhausted, Outside In will assume that an input document is encoded in the character set specified by this option. This is most often used when reading plain-text files, but may also be used when reading HTML or PDF files.

14.4.2.4 DefaultRenderFont

OIT Option ID: SCCOPT_DEFAULTPRINTFONT

This option sets the font to use when the chunker-specified font is not available on the system. It is also the font used when the font in source file is not available on the system performing the conversion.

Class members:

string strFaceName

int FontHeight

14.4.2.5 DefaultPageMargins

This option specifies the top, left, bottom and right margins in twips from the edges of the page. For instance, setting all the values to 1440 creates a 1-inch margin on all sides. Page margins will only be applied when formatting word processing, database and spreadsheet files.

Please note all margins are applied before scaling with the PageFitMode option. This option is overridden when the UseDocumentPageSettings option is set to true and print margins are specified in the input document. This option does not affect the output of bitmap, presentation, vector or archive files.

Data Type

Margins

Data

A Margins object with the margins on the 4 sides defined.

Default

1 inch for all margins (1440, 1440, 1440, 1440)

14.4.2.6 DocumentMemoryMode

OIT Option ID: SCCOPT_DOCUMENTMEMORYMODE

This option determines the maximum amount of memory that the chunker may use to store the document's data, from 4 MB to 1 GB. The more memory the chunker has available to it, the less often it needs to re-read data from the document.

Data

- SMALLEST: 1 - 4MB

- SMALL: 2 - 16MB

- MEDIUM: 3 - 64MB

- LARGE: 4 - 256MB

- LARGEST: 5 - 1 GB

Default

SMALL: 2 - 16MB

14.4.2.7 EmailHeaders

OIT Option ID: SCCOPT_WPEMAILHEADEROUTPUT

This option controls rendering of email headers.

Data

- ALL: Displays all available email headers.

- STANDARD: Displays "To," "From," "Subject," "CC," "BCC," "Date Sent," and "Attachments" header fields only. The filter outputs any fields not listed above as hidden fields, so they will not display.

- NONE: Displays no email header fields.

- CUSTOM

Default

STANDARD

14.4.2.8 FallbackFormat

This option controls how files are handled when their specific application type cannot be determined. This normally affects all plain-text files, because plain-text files are generally identified by process of elimination, for example, when a file isn't identified as having been created by a known application, it is treated as a plain-text file. It is recommended that None be set to prevent the conversion from exporting unidentified binary files as though they were text, which could generate many pages of "garbage" output.

Data Type

FallbackFormatValue

FallbackFormatValue Enumeration

- Text: Unidentified file types will be treated as text files.

- None: Outside In will not attempt to process files whose type cannot be identified

Default

Text

14.4.2.9 FitHeightToPages

OIT Option ID: SCCOPT_SSPRINTSCALEXHIGH

This option will fit the spreadsheet image to the number of vertical pages specified. The setting for this option will have no effect unless the SSPrintFitToPage option is set to FitToPages.

Data Type

Int32

Default

1

14.4.2.10 FitWidthToPages

OIT Option ID: SCCOPT_SSPRINTSCALEXWIDE

This option will fit the spreadsheet image to the number of horizontal pages specified. The setting for this option will have no effect unless the SSPrintFitToPage option is set to FitToPages.

Data Type

Int32

Default

1

14.4.2.11 FontAliasList

This option enables the capability to specify which font on the system should be used when a specific font referenced in the original file is not available. A different alias can be set for each font desired to be mapped.

Data Type

FontAliases

Data

A FontAliases object with a list of font matchings

Default

Windows PrintAlias default

14.4.2.12 GraphicHeight

OIT Option ID: SCCOPT_GRAPHIC_HEIGHT

This option defines the absolute height in pixels to which exported graphics will be resized. If this option is set and the GraphicWidth option is not, the width of the image will be calculated based on the aspect ratio of the source image. The developer should be aware that very large values for this option or GraphicWidth could produce images whose size exceeds available system memory, resulting in conversion failure.

If you are exporting a non-graphic file (word processing, spreadsheet or archive) and the settings for GraphicHeight and GraphicWidth do not match the aspect ratio of the original document, the exported image will have whitespace added so that the original file's aspect ratio is maintained.

The settings for the GraphicHeightLimit and GraphicWidth options can override the setting for GraphicHeight.

Data Type

Int32

14.4.2.13 GraphicHeightLimit

OIT Option ID: SCCOPT_GRAPHIC_HEIGHTLIMIT

Note that this option differs from the behavior of setting the height of graphics in that it sets an upper limit on the image height. Images larger than this limit will be reduced to the limit value. However, images smaller than this height will not be enlarged when using this option. Setting the height using GraphicHeight causes all output images to be reduced or enlarged to be of the specified height.

Data Type

Int32

14.4.2.14 GraphicOutputDPI

OIT Option ID: SCCOPT_GRAPHIC_OUTPUTDPI

This option allows the user to specify the output graphics device's resolution in DPI and only applies to images whose size is specified in physical units (in/cm). For example, consider a 1" square, 100 DPI graphic that is to be rendered on a 50 DPI device (GraphicOutputDPI is set to 50). In this case, the size of the resulting TIFF, BMP, JPEG, GIF, or PNG will be 50 x 50 pixels.

In addition, the special #define of SCCGRAPHIC_MAINTAIN_IMAGE_DPI, which is defined as 0, can be used to suppress any dimensional changes to an image. In other words, a 1" square, 100 DPI graphic will be converted to an image that is 100 x 100 pixels in size. This value indicates that the DPI of the output device is not important. It extracts the maximum resolution from the input image with the smallest exported image size.

Setting this option to SCCGRAPHIC_MAINTAIN_IMAGE_DPI may result in the creation of extremely large images. Be aware that there may be limitations in the system running this technology that could result in undesirably large bandwidth consumption or an error message. Additionally, an out of memory error message will be generated if system memory is insufficient to handle a particularly large image.

Also note that the SCCGRAPHIC_MAINTAIN_IMAGE_DPI setting will force the technology to use the DPI settings already present in raster images, but will use the current screen resolution as the DPI setting for any other type of input file.

For some output graphic types, there may be a discrepancy between the value set by this option and the DPI value reported by some graphics applications. The discrepancy occurs when the output format uses metric units (DPM, or dots per meter) instead of English units (DPI, or dots per inch). Depending on how the graphics application performs rounding on meters to inches conversions, the DPI value reported may be 1 unit more than expected. An example of a format which may exhibit this problem is PNG.

The maximum value that can be set is 2400 DPI; the default is 96 DPI.

Data Type

Int32

14.4.2.15 GraphicRenderAsPage

OIT Option ID: SCCOPT_GRAPHIC_RENDERASPAGE

GraphicRenderAsPage affects the way raster (bitmapped) images such as TIFF, JPG, and PNG are handled. The default behavior for Image Export is to export such images as copies of the input document, scaled according to the width and height options set by the caller. If GraphicRenderAsPage is enabled, the output produced by Image Export will look like a printed page, with the image placed on a white rectangle representing a virtual page. As usual, the dimensions of the entire image, including the virtual page, will be controlled by the normal Image Export output width and height settings. The margins into which the image will be placed will be controlled by existing Outside In print margin options. The image itself will be attempted to be scaled to its true (physical) size, or scaled down to fit within the margins if necessary.

Data Type

bool

Data

- true: Raster file images are fit to page.

- false: Raster file images are not fit to page.

Default

false

14.4.2.16 GraphicSizeLimit

OIT Option ID: SCCOPT_GRAPHIC_SIZELIMIT

This option is used to set the maximum size of the exported graphic in pixels. It may be used to prevent inordinately large graphics from being converted to equally cumbersome output files, thus preventing bandwidth waste.

This setting takes precedence over all other options and settings that affect the size of a converted graphic.

When creating a multi-page TIFF file, this limit is applied on a per page basis. It is not a pixel limit on the entire output file.

Data Type

Int32

14.4.2.17 GraphicSizeMethod

OIT Option ID: SCCOPT_GRAPHIC_SIZEMETHOD

This option determines the method used to size graphics. The developer can choose among three methods, each of which involves some degree of trade off between the quality of the resulting image and speed of conversion.

Using the quick sizing option results in the fastest conversion of color graphics, though the quality of the converted graphic will be somewhat degraded. The smooth sizing option results in a more accurate representation of the original graphic, as it uses anti-aliasing. Antialiased images may appear smoother and can be easier to read, but rendering when this option is set will require additional processing time. The grayscale only option also uses antialiasing, but only for grayscale graphics, and the quick sizing option for any color graphics.

The smooth sizing option does not work on images which have a width or height of more than 4096 pixels.

Data Type

- GRAPHICSIZEMETHOD_VALUES

14.4.2.18 GraphicWidth

OIT Option ID: SCCOPT_GRAPHIC_WIDTH

This option defines the absolute width in pixels to which exported graphics will be resized. If this option is set and the GraphicHeight option is not, the height of the image will be calculated based on the aspect ratio of the source image. The developer should be aware that very large values for this option or GraphicHeight could produce images whose size exceeds available system memory, resulting in conversion failure.

If you are exporting a non-graphic file (word processing, spreadsheet or archive) and the settings for GraphicHeight and GraphicWidth do not match the aspect ratio of the original document, the exported image will have whitespace added so that the original file's aspect ratio is maintained.

The settings for the GraphicHeightLimit and GraphicWidthLimit options can override the setting for GraphicWidth.

Data Type

Int32

14.4.2.19 GraphicWidthLimit

OIT Option ID: SCCOPT_GRAPHIC_WIDTHLIMIT

This option allows a hard limit to be set for how wide in pixels an exported graphic may be. Any images wider than this limit will be resized to match the limit. It should be noted that regardless whether the GraphicHeightLimit option is set or not, any resized images will preserve their original aspect ratio.

Note that this option differs from the behavior of setting the width of graphics by using GraphicWidth in that it sets an upper limit on the image width. Images larger than this limit will be reduced to the limit value. However, images smaller than this width will not be enlarged when using this option. Setting the width using GraphicWidth causes all output images to be reduced or enlarged to be of the specified width.

Data Type

Int32

14.4.2.20 GridMaxPageHeight

OIT Option ID: SCCOPT_MAXSSDBPAGEHEIGHT

Normally, the size of images generated from spreadsheet worksheets and database tables is limited to the size of the page defined by the input document's page size information and how the UseDocumentPageSettings, GraphicWidth and GraphicHeight options are set. If, after scaling is factored in, the resulting image is too large to fit on a single page, it is split up into multiple pages.

The GridMaxPageWidth and GridMaxPageHeight options are used to change the size of a page to match the scaled size of the page being rendered - within limits. The key reason for those limits is that rendering very large pages can easily overwhelm the memory available on the system. When using this feature, a calculation should be made to be sure that the values passed in work within said memory limits. The values for these two options will override the current page dimensions if necessary.

Data Type

Int32

Data

The maximum page height (including margins) specified in twips (1440 twips are in 1 inch). If the value specified is smaller than the page height, then an error will be returned.

14.4.2.21 GridMaxPageWidth

OIT Option ID: SCCOPT_MAXSSDBPAGEWIDTH

See the documentation for GridMaxPageHeight for a full discussion of how this option works and interacts with other options affecting the page size of images generated from spreadsheet and database pages.

Data Type

Int32

Data

The maximum page width (including margins) specified in twips (1440 twips are in 1 inch). If the value specified is smaller than the page width, then Image Export will return an error.

14.4.2.22 IECondCommentMode

OIT Option ID: SCCOPT_HTML_COND_COMMENT_MODE

Some HTML input files may include "conditional comments", which are HTML comments that mark areas of HTML to be interpreted in specific versions of Internet Explorer, while being ignored by other browsers. This option allows you to control how the content contained within conditional comments will be interpreted by Outside In's HTML parsing code.

Data

- NONE: Don't output any conditional comment

- IE5: Include the IE5 comments

- IE6: Include the IE6 comments

- IE7: Include the IE7 comments

- IE8: Include the IE8 comments

- IE9: Include the IE9 comments

- ALL: Include all conditional comments

14.4.2.23 IgnorePassword

OIT Option ID: SCCOPT_IGNORE_PASSWORD

This option can disable the password verification of files where the contents can be processed without validation of the password. If this option is not set, the filter should prompt for a password if it handles password-protected files.

Data Type

bool

14.4.2.24 ISODateTimes

OIT Option ID: SCCOPT_FORMATFLAGS

When this flag is set, all Date and Time values are converted to the ISO 8601 standard. This conversion can only be performed using dates that are stored as numeric data within the original file.

Data

bool

Default

false

14.4.2.25 JPEGQuality

OIT Option ID: SCCOPT_JPEG_QUALITY

This option allows the developer to specify the lossyness of JPEG compression. The option is only valid if the dwOutputID parameter of the EXOpenExport function is set to FI_JPEGFIF, FI_PDF, FI_PDFA, or FI_PDFA_2.

Data Type

Int32

Data

A value from 1 to 100, with 100 being the highest quality but the least compression, and 1 being the lowest quality but the most compression.

Default

100

14.4.2.26 LotusNotesDirectory

OIT Option ID: SCCOPT_LOTUSNOTUSDIRECTORY

This option allows the developer to specify the location of a Lotus Notes or Domino installation for use by the NSF filter. A valid Lotus installation directory must contain the file nnotes.dll.

Data

A path to the Lotus Notes directory.

Default

If this option isn't set, then OIT will first attempt to load the Lotus library according to the operating system's PATH environment variable, and then attempt to find and load the Lotus library as indicated in HKEY_CLASSES_ROOT\Notes.Link.

14.4.2.27 PageDirection

OIT Option ID: SCCOPT_SSPRINTDIRECTION

This option controls the pattern in which the pages are rendered, either across first and then down, or down first and then across.

This option is overridden when the UseDocumentPageSettings option is set to true and print direction is specified in the input document.

Data Type

PAGEDIRECTION_VALUES

Default

PageDirectionDown

14.4.2.28 PageFitMode

OIT Option ID: SCCOPT_DBPRINTFITTOPAGE

OIT Option ID: SCCOPT_SSPRINTFITTOPAGE

This option scales a spreadsheet file or database image to a certain percent or to a page width or height. However, in an effort to preserve readability after scaling, Image Export will not shrink a database document to under approximately one-third of its original size.

It should be noted that when this option is set to NoMap, the pages of the database file are printed down first and then across.

Please note that any margins applied as a result of settings for the DefaultPrintMargins option will be included in any scaling that is applied to the output image as a result of settings for this option.

This option is overridden when the UseDocumentPageSettings option is set to true and fitting the page to the printer's image limits is specified in the input document.

Data

- NoMap: No scaling is performed on the spreadsheet or database image. It will render in its original size onto as many pages as are required to fit the data.

- FitToWidth: Scale the spreadsheet or database image in the rendered image so it is no larger than one page wide.

- FitToHeight: Scale the spreadsheet or database image in the rendered image so it is no larger than one page high.

- Scale: Scale the spreadsheet or the database image in the rendered image using the scale value stored in the PageScalePercent option.

- FitToPages: Scale the spreadsheet or the database image in the rendered image to fit to the number of pages specified in the FitHeightToPages and FitWidthToPages options. Since aspect ratio is maintained, the lesser of the two dimensions (width or height) will determine the scale factor. Note that if either FitHeightToPages or FitWidthToPages is set to 0, the value in the other option will be nullified.

Default

- Scale: Scales the rendered image of the spreadsheet or database image using the scale value stored in the PageScalePercent option (which is 100 by default).

OIT Option ID: SCCOPT_PRINTSTARTPAGE

OIT Option ID: SCCOPT_PRINTENDPAGE

This option indicates whether the whole file or a selected range of pages should be rendered. When selecting a range, the start and ending pages are specified.

Data Type

PageRange

Data

The page range to be exported.

Default

All pages are printed

14.4.2.30 PageScalePercent

OIT Option ID: SCCOPT_SSPRINTSCALEPERCENT

This option will scale spreadsheet pages by the percentage specified. The option has no effect unless the SSPrintFitToPage option is set to Scale.

Data Type

Int32

Default

100

14.4.2.31 PDFReorderBiDi

OIT Option ID: SCCOPT_PDF_FILTER_REORDER_BIDI

This option controls whether or not the PDF filter will attempt to reorder bidirectional text runs so that the output is in standard logical order as used by the Unicode 2.0 and later specification. This additional processing will result in slower filter performance according to the amount of bidirectional data in the file.

PDFReorderBiDiValue Enumeration

This enumeration defines the type of Bidirection text reordering the PDF filter should perform.

- StandardBiDi: Do not attempt to reorder bidirectional text runs.

- ReorderedBiDi: Attempt to reorder bidirectional text runs.

14.4.2.32 PerformExtendedFI

OIT Option ID: SCCOPT_FIFLAGS

This option affects how an input file's internal format (application type) is identified when the file is first opened by the Outside In technology. When the extended test flag is in effect, and an input file is identified as being either 7-bit ASCII, EBCDIC, or Unicode, the file's contents will be interpreted as such by the export process.

The extended test is optional because it requires extra processing and cannot guarantee complete accuracy (which would require the inspection of every single byte in a file to eliminate false positives.)

Data Type

bool

Data

One of the following values:

- false: When this is set, standard file identification behavior occurs.

- true: If set, the File Identification code will run an extended test on all files that are not identified.

Default

true

14.4.2.33 QuickThumbnail

OIT Option ID: SCCOPT_QUICKTHUMBNAIL

When this option is set to true the technology will render scaled images with a focus on speed and reduced overall memory usage. This focus on speed and memory usage, in some cases, will cause the resulting images to be less readable than when this option is set to false.

Data Type

bool

Data

- true: Render scaled images as quick thumbnails.

- false: Render scaled images completely.

Default

true

14.4.2.34 RenderGridlines

Data Type

bool

Default

true

14.4.2.35 RenderHeadings

OIT Option ID: SCCOPT_DBPRINTHEADINGS

OIT Option ID: SCCOPT_SSPRINTHEADINGS

14.4.2.37 ShowHiddenCells

OIT Option ID: SCCOPT_SSSHOWHIDDENCELLS

This option lets you determine whether or not to show hidden rows or columns when rendering spreadsheets. It is used to expand the widths of cells that are hidden by virtue of having their row height or column width reduced to 0. This is a Boolean option that will leave the data hidden when it is false, and show all hidden rows and columns when it is true, displayed using the default row width or default column height.

Data Type

bool

Default

false

14.4.2.38 ShowHiddenSpreadSheetData

The setting for this option determines whether or not hidden data (hidden columns, rows or sheets) in a spreadsheet will be included in the output. When set to false (the default), the hidden elements are not written. When set to true, they are placed in the output in the same manner as regular spreadsheet data.

Data Type

bool

Default

false

14.4.2.39 StrictFile

When an embedded file or URL can't be opened with the full path, OutsideIn will sometimes try and open the referenced file from other locations, including the current directory. When this option is set, it will prevent OutsideIn from trying to open the file from any location other than the fully qualified path or URL.

Data Type

bool

Default

false

14.4.2.40 TIFFByteOrder

This option determines the byte order used within the file.

Data

- Transmission: TIFF files intended for electronic transmission (example fax)

- AllOff

Default

AllOff

14.4.2.44 TIFFMultiPage

This allows the developer to specify whether the output creates a single multi-page TIFF file or individual single page files. When this flag is true, the output of multiple pages from one input document will generate a single file with a separate image for each page converted.

Data Type

bool

Default

false

14.4.2.45 TimeZoneOffset

OIT Option ID: SCCOPT_TIMEZONE

This option allows the user to define an offset to GMT that will be applied during date formatting, allowing date values to be displayed in a selectable time zone. This option affects the formatting of numbers that have been defined as date values. This option will not affect dates that are stored as text. To query the operating system for the time zone set on the machine, specify TimeZoneOffset_UseNative.

Note:

Daylight savings is not supported. The sent time in msg files when viewed in Outlook can be an hour different from the time sent when an image of the msg file is created.

Data Type

Int32

Data

Integer parameter from -96 to 96, representing 15-minute offsets from GMT. To query the operating system for the time zone set on the machine, specify SCC_TIMEZONE_USENATIVE.

Default

- 0: GMT time

14.4.2.46 TransparencyColor

OIT Option ID: SCCOPT_GRAPHIC_TRANSPARENCYCOLOR

This option allows the user to set the color used as the "transparency color" in the output graphic file. Naturally, this option is only used when the selected output graphic file format supports transparency (GIF and PNG only). If the option is not set, the default behavior is to use the same color value that the input file used as the transparency color.

Use the (r, g, b) macro to create the color value to pass to this option. The red, green and blue values are percentages of the color from 0-255 (with 255 being 100%). Note that this macro should be used to set a variable and that variable should then be passed to the set option routine (instead of trying to use the macro as part of the set option call directly).

Since there is no way to "unset" an option once it has been set, the developer may set the option to DefaultTransparencyColor if they wish to revert to the default behavior.

Class members:

byte Red

byte Green

byte Blue

14.4.2.47 UnmappableCharacter

OIT Option ID: SCCOPT_UNMAPPABLECHAR

This option selects the character used when a character cannot be found in the output character set. This option takes the Unicode value for the replacement character. It is left to the user to make sure that the selected replacement character is available in the output character set.

Data Type

UShort

Data

The Unicode value for the character to use.

Default

- 0x002a = "*"

14.4.2.48 UseDocumentPageSettings

OIT Option ID: SCCOPT_USEDOCPAGESETTINGS

This option is used to select the document's page layout information when rendering.

If true, the document's native (or author selected) page margins, paper size, page scaling and page orientation are used when available from the filter.

The values of the DefaultPrintMargins, RenderGridlines, RenderHeadings, PageDirection, and PageFitMode options are overridden if this option is set to true and the properties associated with those options are specified in the input document. Additionally, print area and page breaks in spreadsheet documents are ignored unless this option is set to true.

If false, the page margins, size, orientation and scaling are set to specific values rather than those in the native document. The page size is forced to 8 1/2" x 11" in portrait orientation, but this may be changed by setting the GraphicHeight and/or GraphicWidth options. The margins are forced 1" all around, but may be changed by setting the defaultMargins option. The scaling for the document will be set to 100%, although this may be changed by setting any of the various scaling options.

It should be noted that this option also affects page orientation for both input spreadsheets and word processing documents.

Data Type

bool

Default

true
